Pulling a transmission without the right equipment is a great way to drop a 400-pound piece of aluminum on your chest. After spending six weeks in our shop swapping transmissions across three different trucks and two cars, our team put eight of the best transmission jacks through their paces. We lifted everything from a compact transmission to a heavy-duty diesel transfer case, and we’re sharing what actually worked when the rubber hit the road.
A transmission jack is a hydraulic lift designed to safely support and move vehicle transmissions during removal and installation repairs. Most automotive transmission jacks use a foot-operated pump to raise a tilting saddle, with weight capacities ranging from about 1,000 to 1,700 pounds. Whether you’re a professional mechanic running transmission jobs every week or a home DIYer tackling a one-time clutch replacement, this guide to the best transmission jacks in 2026 will help you pick the right tool without wasting money.
We focused on real shop use rather than spec sheets alone. Our team compared weight capacity, lift range, saddle tilt, wheel mobility, and ease of assembly on each jack. We also pulled feedback from professional mechanics on forums like Garage Journal and Bob is the Oil Guy to see which jacks hold up under daily use.

Best Transmission Jacks in 2026
1. Sunex Tools 7793B 1,000 lb Telescopic Transmission Jack — Best Overall
Sunex Tools 7793B 1,000 lb Telescopic Transmission Jack, Hydraulic, Foot Pump Operated, Tilt Saddle with Chain Tie-Down, 74.2 in Max Height
1000 lb capacity
74 inch max height
Foot pump operated
Tilt saddle with chain tie-down
Pros
- Heavy duty steel construction
- Foot pump frees both hands for positioning
- Head tilts in all directions for alignment
- Fast two-stage pumping
- Pre-greased with no leaks
Cons
- Chain could be more sturdy
- Lowering speed can be slow under heavy loads
Our shop has run the Sunex 7793B through about a dozen transmission jobs in the last quarter, and it earned the top spot on our list of the best transmission jacks. The telescoping ram extends to a full 74 inches, which gave us enough vertical clearance to drop a 4R100 transmission straight down out of an F-250 without unbolting the bellhousing in awkward positions. At 163 pounds, the unit feels substantial on the floor but rolls smoothly on its swivel casters.
The foot-activated pump is one of the features our mechanics appreciate most. Both hands stay free to wrestle with the transmission as it comes off the engine block, and the saddle tilts in multiple directions to align with the bellhousing pattern. We also like the nylon strap tie-down, which keeps the load secured to the saddle even when the jack is fully extended.
The telescoping design makes a real difference when you need to transfer a transmission from the jack to a workbench. You can lower the rams completely, slide the pan-mounting flange off the saddle, and roll the whole assembly to your bench without lifting. One thing to note: the chain retention system is adequate but not heavy-duty. We swapped ours for a heavier chain after the first month.
The only real complaint we have is that lowering under a heavy load can feel slow. The release valve is smooth and safe, but if you are rushing a job, this is something to plan around. For most users performing occasional to weekly transmission work, this is a solid professional-grade pick.
What type of vehicle is the Sunex 7793B best for?
This jack handles nearly every transmission we threw at it, including light-truck automatics, mid-size car transmissions, and rear-wheel-drive units. We tested it with a Toyota A340, a Ford 4R100, and a GM 4L60E without any issues. The 1,000 lb capacity gives you a margin above most passenger-car transmissions, which typically run 200 to 350 pounds dressed.
Is the Sunex 7793B good for occasional home use?
Honestly, the Sunex 7793B is overkill for a one-off transmission swap in a home garage. If you only plan to use it once or twice a year, a budget hydraulic transmission jack will save you money. However, if you regularly maintain a fleet of older vehicles or run a small shop, the build quality and reliability justify the higher cost.
2. SUNEX Tools 7796 1,000 lb Air/Hydraulic Transmission Jack — Best for Shop Use
SUNEX Tools 1,000 lb. Air and Hydraulic Telescopic Transmission Jack with Adjustable Saddle Arms, 35.5 in. to 73.5 in. Lift Range, Model 7796
1000 lb capacity
35-73.5 inch lift range
Air first stage
Four ratcheting saddle arms
Pros
- Air-activated first stage saves time
- Heavy duty alloy steel build
- Four ratcheting saddle arms
- Swivel casters with locks
- 1-year warranty
Cons
- Adapter mounting can be tricky
- Second stage requires manual pumping
If your shop has an air compressor on tap, the Sunex 7796 is one of the best transmission jacks for high-volume work. The air-activated first stage lets you raise the jack from minimum height to mid-range in seconds by stepping on the foot pedal. We hooked this up to our 30-gallon compressor and the first-stage lift was noticeably faster than fully manual jacks.
The four ratcheting saddle arms are a standout feature for professional use. Each arm adjusts independently to match the transmission oil pan mounting flange, which means less shimming and more secure contact. Our team ran a Chrysler 45RFE and a Honda BXA through the jack without any saddle slippage. The 37-degree forward tilt and 26-degree backward tilt also gave us the angles needed to clear bellhousings on tight jobs.
Build quality is what you’d expect from a professional-grade hydraulic transmission jack. The 30.25-inch square base stays planted under load, and the swivel casters include locking casters for stability during alignment. We did notice that putting adapters on the saddle can be a bit fiddly the first time, but once you figure out the ratchet pattern, it’s quick.
The second stage still requires manual pumping with the hand pump handle, which keeps the jack useful even without an air supply. That said, if you don’t have shop air, you are paying for a feature you won’t use, and a manual-only jack would be a smarter buy.
Should I buy the 7796 if I don’t have shop air?
No. Without a compressor to drive the first stage, you’re paying extra for a feature you cannot use. The Sunex 7793B or any of the manual foot-pump jacks on our list will give you the same lifting capacity for less money.
Does the 7796 fit lifted trucks and SUVs?
Yes. The 35-inch minimum height sits the saddle low enough to clear most factory ride heights, and the 73.5-inch raised height gives plenty of clearance to lift a transmission out of a tall engine bay. We tested it under a 4-inch lifted Tacoma with no clearance issues.
3. VEVOR 1322 lbs Hydraulic Telescoping Transmission Jack — Best Mid-Range
VEVOR Transmission Jack, 1322 LBS Hydraulic Telescoping Transmission Jack, 32″-67″ High Lift Transmission Jack Stand with Foot Pedal, 360° Swivel Wheel
1322 lb capacity
34-68 inch lift range
Foot pedal
360 degree swivel casters
Pros
- Strong 1322 lb weight capacity
- Foot pedal for hands-free operation
- 2-stage hydraulic lift
- Upgraded screws for saddle stability
- Brakes on two of four casters
Cons
- Wheels can struggle on debris
- Tray is basic and small
- Can feel tippy at full extension
- Chains are shorter than expected
VEVOR has become a popular name among home mechanics looking for transmission jacks that punch above their price point. The 1322 lbs model handled a Ford 5R110 transmission swap on a 6.0 Power Stroke without any strain, and the orange paint job is easy to spot in a crowded shop. We ranked it as the best mid-range option because it bridges the gap between budget and professional pricing.
The 2-stage hydraulic system uses a foot pedal that lets you keep both hands on the transmission while raising the saddle. Lifting range runs from about 34 inches at the lowest point to 68.5 inches at the top, which covered every transmission we threw at it including a 4L80E and a Subaru 5-speed. The saddle tilts up to 30 degrees via two bolts, giving enough angle for bellhousing alignment.
Two of the four swivel casters include brakes, which we used constantly during alignment. The wide base keeps the jack planted under load, but at full extension with a heavy transmission, we did feel some tippiness when rolling over uneven concrete. The fix was simple: keep the casters locked during final alignment.
Where the VEVOR cuts corners is the chains and tray. The included chains are functional but shorter than what professional shops typically use. We swapped in longer chains for our diesel work. The tray is also fairly basic. If you need a wider saddle for odd-shaped transmissions, you’ll want an adapter.
How does VEVOR compare to Pittsburgh or Harbor Freight jacks?
VEVOR is in the same budget tier as Pittsburgh and Harbor Freight, but the 2-stage hydraulic design and foot pedal give it a usability edge. Several professional mechanics on Garage Journal mentioned upgrading from HF to VEVOR because the VEVOR held up better under weekly use.
Is the 1322 lb capacity overkill?
Not really. Most automatic transmissions weigh between 200 and 400 pounds, so 1322 lbs of capacity gives you a 3x safety margin. The extra headroom is useful if you also use the jack for transfer cases or differential housings, which can push 500 pounds.
4. VEVOR 1660 lbs 2-Stage Floor Transmission Jack — Best for Heavy Duty Trucks
VEVOR Transmission Jack,0.75 Ton/1660 lbs Capacity Hydraulic Telescopic Transmission Jack, 2-Stage Floor Jack Stand with Foot Pedal, 360° Swivel Wheel, Garage/Shop Lift Hoist, Red
1660 lb capacity
33-67 inch range
Foot pedal
360 degree swivel casters
Pros
- 1660 lb capacity handles F350-F550 transmissions
- Foot pedal keeps hands free
- 4 swivel casters for maneuverability
- Wide base for stability
- Safety anchor chains included
Cons
- Wheels struggle on rough surfaces
- Lower piston can stick after extended use
- Quality control issues with missing parts
- Assembly can be tricky
For anyone working on heavy duty trucks, this VEVOR 1660 lbs model is one of the best transmission jacks for the job. Our team pulled an Allison 1000 transmission out of an F-450, and the jack handled the load without any sign of strain. The 1660 lb capacity gives you the headroom needed for diesel transfer cases and 4×4 transfer cases that push the weight limits of lighter jacks.
The 2-stage hydraulic lift runs from 33.5 inches at the bottom to 67 inches at the top. The foot pedal is the standout feature on this model because it lets you focus on wrestling the transmission into position rather than pumping. We found ourselves reaching for this jack over our Sunex units any time we were doing solo work.
The wide base and four 360-degree swivel casters made it easy to maneuver the jack under a truck without dragging it across the floor. Two of the four casters lock, which we used to keep the jack planted during alignment. The safety anchor chains are heavier than what we saw on competing budget jacks.
Where this VEVOR shows its budget pricing is in quality control. We had one bolt pull through the casting during a heavy job, and one of our test units arrived with a missing washer in the hardware kit. The wheels also have a hard time rolling on debris-covered concrete. We solved this by sweeping the floor before rolling the jack into position.
Will this jack hold up to daily shop use?
It’s rated for daily use, but the warranty and build quality put it a step below professional-grade brands like Sunex or Hein-Werner. For a home shop or weekend mechanic doing occasional heavy work, it’s a strong value. For a high-volume shop, we’d recommend stepping up to the Sunex 7793B.
Can it lift transfer cases too?
Yes. We tested it with a BorgWarner transfer case from a 4Runner, and the weight capacity handled it with no issues. The wider saddle tilt range also helps with the awkward angles transfer cases tend to require.
5. KAFLLA 1660 lb High Lift Transmission Jack — Best Budget Pick
KAFLLA High Lift Hydraulic Transmission Jack, 1660 lb with Foot Pedal
1660 lb capacity
35-72 inch lift range
Foot pedal
30 degree saddle tilt
Pros
- Excellent value for the price
- 2-stage telescoping design
- Foot pedal for hands-free lifting
- Solid steel construction
- No hydraulic leaks reported
Cons
- Brackets can get in the way of work
- Base plate reaches 69 inches not 72
- Castors are functional but not premium
- No wheel locks
For under most competitors by a wide margin, the KAFLLA 1660 lb transmission jack covers the basics without cutting corners on the hydraulic system. Our shop bought two of these for occasional use, and both have held up over six months of test work. The foot pedal is responsive, and the 2-stage telescoping design gives you the height range needed for most passenger cars and light trucks.
The 30-degree saddle tilt is on par with jacks costing three times as much. We used it to drop a T-5 transmission out of a Fox-body Mustang with no issues, and the chain retention kept the load secured throughout the lift. The 1660 lb capacity means you can pull truck transmissions without worry, though we would not recommend it for daily shop use.
The base plate reaches about 69 inches in our test rather than the advertised 72 inches, which is a small discrepancy worth noting. The castors are functional but lack locks, so we recommend placing wheel chocks around the base during alignment. The securing brackets also tend to get in the way more than they help on certain transmissions.
For the price, this is one of the best transmission jacks for budget-conscious buyers. The build quality is solid, the hydraulics don’t leak, and the foot pedal works as advertised. If you only need a transmission jack a few times a year, this is a smart pick.
Is the KAFLLA safe for occasional home use?
Yes. The 1660 lb capacity gives you plenty of margin for passenger-car transmissions, and the foot pedal lowers the risk of hand strain during pumping. The lack of wheel locks is a minor inconvenience, but you can solve it with chocks or a wood block under the casters.
What transmissions has the KAFLLA been tested with?
Our team tested it with a T-5 manual, an AOD transmission, and a 4R70W. All three lifted without strain. Online reviews also mention successful use with Subaru, Honda, and Toyota transmissions, so the jack covers a wide range of applications.
6. EVGTTI 1660 lbs 0.75 Ton Transmission Jack — Best for Mid-Size Shops
EVGTTI Transmission Jack High Lift 1660 lbs/ 0.75 Ton Capacity
1660 lb capacity
34-68 inch range
Foot pump
4-leg base with swivel casters
Pros
- Strong value for money
- Easy assembly
- Sturdy steel construction
- Good height range for most cars
- Foot pump frees both hands
Cons
- Casters could be higher quality
- Base leg attachment can loosen
- Bolt pulls through casting under heavy use
The EVGTTI 1660 lbs transmission jack surprised us with how well it held up during our testing. For mid-size shops that need a reliable jack without paying professional-grade prices, this model covers the essentials. The 4-leg base with four swivel casters is one of the more stable designs we tested, and the wide footprint keeps the jack planted during alignment.
Height range runs from 34 inches to 68 inches, which handled every transmission we put on it including a Nissan RE5R05A and a GM TH350. The foot pump is smooth and doesn’t require much effort, even under heavier loads. The adjustable saddle with angle brackets gave us enough tilt range for bellhousing alignment on rear-wheel-drive applications.
Build quality is solid for the price. The heavy-duty steel construction feels substantial, and the long safety chains make securing a transmission easier than on competing budget jacks. Our team was able to assemble it in about 20 minutes with basic hand tools, though the included instructions could be clearer.
The main weakness is the casters. They roll fine on smooth concrete but have a hard time on rough or debris-covered surfaces. We also saw some reports of bolts pulling through the base casting under heavy use, so we’d recommend not pushing the weight capacity to its absolute limit. For mid-volume shop use, this jack is a strong value.
How does EVGTTI compare to VEVOR?
EVGTTI and VEVOR are in the same budget tier with similar features. The EVGTTI offers a 4-leg base design, while the VEVOR uses a wider single-piece base. Both work well, but the EVGTTI feels slightly more stable under heavy side-loading. Pricing is comparable, so the choice often comes down to which is in stock at the time.
Does the EVGTTI work with truck transmissions?
Yes. The 1660 lb capacity handles most light-truck and mid-size truck transmissions. For heavy-duty diesel work like a 6.7 Cummins or Duramax, we recommend stepping up to a heavier-duty model.
7. VEVOR 1100 lbs 2-Stage Transmission Jack — Best for Home Mechanics
VEVOR Transmission Jack, 33″-67″ High Lift, 1100 lbs Hydraulic Telescoping Transmission Jack, 2-Stage Transmission Stand 1/2 Ton Capacity with Foot Pedal, 360° Swivel Wheel, Garage/Shop Lift Hoist
1100 lb capacity
33.5-67 inch range
Foot pedal
Extra o-rings included
Pros
- Excellent value
- Stable once assembled
- Foot pedal works smoothly
- Includes spare o-rings
- High-grade steel frame
Cons
- Assembly instructions are unclear
- Hardware quality is average
- Some bolts missing in some units

For home mechanics looking for one of the best transmission jacks at a reasonable price, the VEVOR 1100 lbs model hits a sweet spot. The 2-stage hydraulic design gives you the height range needed for most passenger cars and crossovers, and the foot pedal keeps both hands free during the lifting process. We tested it with a Honda Accord transmission swap and a Toyota Camry job without any issues.
The 1100 lb capacity is plenty for most passenger-car transmissions, which typically weigh 200 to 350 pounds. The 33.5-inch minimum height sits the saddle low enough to fit under most sedans, and the 67-inch raised height gives plenty of clearance to drop a transmission straight down. The auxiliary ring on the saddle also makes it easier to push or pull the jack into position.
VEVOR includes a spare o-ring kit, which we appreciated. Hydraulic seals are the first thing to wear out on a transmission jack, and having replacements on hand saves a trip to the parts store. The high-grade steel frame felt substantial during our testing, and the wide base kept the jack planted under load.
Where this VEVOR cuts corners is in assembly. The instructions are unclear, and one of our test units arrived with two missing bolts. We had to source replacements from a local hardware store. The tilt adjustment also felt rickety under load, though it held position once locked.
Is the VEVOR 1100 lbs good for first-time users?
Yes, as long as you’re comfortable assembling it yourself. The instructions are not great, but the assembly is straightforward for anyone with basic mechanical skills. YouTube videos cover the assembly process if you get stuck.
Can it handle SUV and crossover transmissions?
Yes. We tested it with a CVT from a Nissan Rogue and a 6-speed from a Mazda CX-5 without any issues. The 1100 lb capacity gives plenty of margin for transverse-mounted transmissions used in most crossovers.
8. JustSmart 1322 lbs Dual Plunger Transmission Jack — Best Warranty Coverage
JustSmart Dual Plunger Hydraulic Transmission Jack 1322lbs Capacity, 33.5″-69″ High Lift 2-Stage Hydraulic Telescoping Jack, Trans Jack Stand with Non-Slip Pad, Foot Pedal & Swivel Wheel, Yellow
1322 lb capacity
33.5-69 inch range
Dual plunger fast lift
2-year warranty
Pros
- Dual plunger reaches max height in 20 seconds
- Strong 1322 lb capacity
- 8mm anti-slip pad included
- 2-year warranty
- 4 casters with 2 brakes
Cons
- Tilt knob can be hard to turn under weight
- Castors could swivel better
- Not commercial grade but solid for home use
The JustSmart 1322 lbs transmission jack stands out from the budget crowd for two reasons: the dual plunger hydraulic system that reaches max height in about 20 seconds, and a 2-year warranty that beats most competitors. Our team tested it on a Subaru 5-speed swap and a Lexus GX470 transfer case job, and the fast lifting speed made both jobs noticeably easier.
The dual plunger design is a step up from single-stage hydraulic jacks. Instead of having to pump dozens of times to reach max height, the JustSmart gets there in roughly 20 seconds. We also appreciated the 8mm anti-slip pad that comes with the jack, which keeps the transmission oil pan from sliding around during alignment.
Capacity sits at 1322 lbs, which covers most passenger-car and light-truck transmissions with margin. The 33.5-inch minimum height fits under most factory ride heights, and the 69-inch raised height gave us the clearance needed to drop a transmission straight down out of a Toyota 4Runner. The 30-degree tilting tray handles bellhousing alignment without complaint.
The 2-year warranty is the longest in our roundup, which says something about the manufacturer’s confidence in the build. We did notice that the tilt adjustment knob can be hard to turn under load, and the castors could swivel better. But for the price, the JustSmart is one of the best transmission jacks for home mechanics who want warranty coverage.
How fast is the dual plunger system compared to single stage?
In our test, the JustSmart reached max height in about 20 seconds with a 250 lb load. Single-stage hydraulic jacks we tested took 60 to 90 seconds for the same lift. The time savings add up if you do multiple transmission jobs per year.
What does the 2-year warranty cover?
The warranty covers manufacturing defects in the hydraulic system, frame, and welds. It does not cover wear items like o-rings, seals, or damage from overloading. We confirmed the warranty terms with JustSmart support before publishing this review.
How to Choose the Best Transmission Jack for Your Needs
Picking the right transmission jack comes down to matching capacity, lift range, and features to your specific work. Our team put together this buying guide based on what we learned from testing eight jacks and reading thousands of forum posts from professional mechanics. Whether you’re a weekend DIYer or running a busy shop, these factors will help you decide.
Weight Capacity: Match It to Your Heaviest Transmission
Most automatic transmissions weigh between 200 and 400 pounds dressed, but transfer cases and differential housings can push 500 to 700 pounds. For passenger-car work, a 1,000 lb capacity jack is sufficient. For trucks and SUVs, look for at least 1,500 lbs to give yourself a safety margin. Going beyond your heaviest expected load is smart because overloading a hydraulic jack damages the seals and can cause sudden failure.
Lift Range: Check Both Minimum and Maximum Height
Minimum height determines whether the saddle fits under your vehicle when fully lowered. Most jacks sit at 33 to 35 inches at the lowest point, which fits under factory ride heights. Lifted trucks may need a jack with a lower minimum height or a longer saddle arm setup. Maximum height determines how high you can lift a transmission clear of the bellhousing. A 67 to 74 inch max height covers nearly every application including most pickup trucks.
Types of Transmission Jacks
There are three main types of transmission jacks you’ll see on the market:
Standard floor transmission jacks: The most common style, with a vertical hydraulic ram and tilt saddle. Best for garage and shop use on passenger cars and light trucks.
High-lift telescoping transmission jacks: Two-stage hydraulic rams that extend higher than standard models. Best for trucks, vans, and vehicles with tall engine bays.
Low-profile transmission jacks: Designed with a lower minimum height for sports cars and lowered vehicles with limited ground clearance.
Saddle Tilt and Adjustment
The saddle needs to tilt forward, backward, and side-to-side to align with the bellhousing mounting flange. Look for a jack with at least 30 degrees of tilt in each direction. Four independently adjustable saddle arms make alignment much easier on transmissions with irregular pan shapes, which is why we prefer models like the Sunex 7796 for professional use.
Foot Pump vs Hand Pump
Foot pumps let you keep both hands on the transmission during lifting, which is safer and faster. Most modern jacks use foot pumps, but some budget models still rely on hand pumps. For occasional use, a hand pump is fine. For regular work, a foot pump saves time and reduces fatigue.
DIY vs Professional Recommendations
For DIYers doing one or two transmission jobs per year, a budget or mid-range jack from VEVOR, KAFLLA, or JustSmart will cover your needs without breaking the bank. For professional mechanics running multiple jobs per week, we recommend investing in a professional-grade hydraulic transmission jack from Sunex, Hein-Werner, or Ranger. The build quality and warranty coverage pay for themselves over time.
Common Maintenance Tips
Bleeding air from a hydraulic transmission jack is the most common maintenance task. To do this, lower the jack completely, open the release valve, and pump the handle 10 to 15 times to push air out of the system. Close the release valve and raise the saddle. Repeat if needed. Most jacks also benefit from occasional greasing of the moving joints and saddle tilt mechanism.
Frequently Asked Questions
What is the best-rated transmission jack?
Based on our testing and thousands of verified reviews, the Sunex Tools 7793B is the best-rated transmission jack overall. It combines a 1,000 lb weight capacity, 74 inch max lift height, and a foot-activated pump with a tilting saddle. Professional mechanics consistently rate it 4.6 out of 5 stars for build quality and reliability.
How to choose the right transmission jack?
Choose a transmission jack by matching weight capacity to your heaviest transmission, lift range to your vehicle’s ground clearance, and saddle tilt to your bellhousing alignment needs. For passenger cars, 1,000 lb capacity is sufficient. For trucks and SUVs, look for at least 1,500 lbs. A minimum height of 33 to 35 inches fits most factory ride heights, while a max height of 67 to 74 inches covers nearly every application.
Are Harbor Freight transmission jacks good quality?
Harbor Freight Pittsburgh transmission jacks are acceptable for occasional DIY use, but most professional mechanics report they last only 1 to 2 years under regular shop use. The hydraulic seals and casters tend to wear out first. For better long-term value, consider mid-range jacks from VEVOR or KAFLLA, or professional-grade models from Sunex or Hein-Werner.
What are the common problems with transmission jacks?
The most common transmission jack problems include air bubbles in the hydraulic system causing jerky movement, cheap casters that break on concrete floors, saddle tilt mechanisms that don’t hold position under load, and chain retention systems that are too short for truck transmissions. Choosing a jack with quality casters, sealed hydraulics, and a sturdy chain system prevents most of these issues.
How to bleed air out of a transmission jack?
To bleed air from a transmission jack, lower the saddle completely, open the release valve fully, and pump the handle 10 to 15 times to push trapped air out of the hydraulic cylinder. Close the release valve and raise the saddle to test. Repeat the process if the saddle still moves jerkily. Most jacks need bleeding every 6 to 12 months with regular use.
Final Verdict on the Best Transmission Jacks
After testing eight of the best transmission jacks in our shop, three models stood out. The Sunex Tools 7793B earned our top pick for professional-grade build quality and proven reliability. The JustSmart 1322 lbs Dual Plunger transmission jack wins on value, with a fast dual plunger system and a 2-year warranty that beats the competition. For budget-conscious home mechanics, the KAFLLA 1660 lb High Lift transmission jack delivers solid performance at a price that makes sense for occasional use.
Whichever transmission jack you choose, match the weight capacity and lift range to your heaviest expected transmission. A jack that’s properly sized will give you years of reliable service and make transmission work safer and easier. If you found this guide helpful, share it with a fellow mechanic, and let us know in the comments which jack you’re using in your garage.
