Buying guide: the best transmission jack for diesel trucks
Capacity first
A diesel truck gearbox is heavy, so capacity comes first. The 1100 lb listings suit heavier gearboxes, while the 450 lb listings suit lighter car and light truck gearboxes. Match the rated capacity to the gearbox in the truck, and leave room above it.
Lift range and saddle tilt
The VEVOR lifts from 33.5 to 67 in, which suits a truck on stands, while the low profile jacks lift from 7 to 23 in for work closer to the floor. A saddle that tilts 30 degrees helps line the gearbox up with the bell housing. Adapters add no lift of their own, so the floor jack underneath sets the range.
Adapters or complete jacks
An adapter turns a floor jack into a transmission jack, and it needs a floor jack with a removable saddle shaft: 1-5/32 in on the labwork adapter and 1-1/5 in on the TUFFIOM adapter. A complete jack rolls on its own casters and needs no other jack. If the garage already has a floor jack with a removable saddle, an adapter takes less floor space.
Safety under the truck
Never get under a vehicle held up by a jack alone. Use rated stands on solid level ground, and follow the owner’s manual lift points. Chains or a strap hold the gearbox on the saddle while it moves. Look over the chains or strap before each use, and keep hands clear while the saddle lowers.
Storage and floor space
The VEVOR stands 33.5 in at its lowest saddle height, so it needs a tall corner of the garage, while the low profile jacks drop to 7 in and slide under a bench. The TUFFIOM adapter measures 13.0 by 11.0 by 7.9 in, so it stores on a shelf. Measure the space before the first job.
A jack is for lifting, not holding. Never work under a vehicle supported only by a jack: set it on rated jack stands, on solid, level ground, at the manufacturer's lift points, chock the wheels, and give the car a firm shake before you go under. Read our Safety Disclaimer.
Garage Fit Check
- Floor space: the VEVOR base measures 25.6 by 33.5 in, and the low profile jacks measure 22.83 by 20.08 in at most.
- Power: none of the 5 picks needs power, and the VEVOR raises with a foot pedal.
- Storage: the low profile jacks drop to 7 in, and the TUFFIOM adapter measures 13.0 by 11.0 by 7.9 in for a shelf.
- Before the first job: confirm the saddle shaft size on an adapter, 1-5/32 in for the labwork adapter and 1-1/5 in for the TUFFIOM adapter, and confirm the rated capacity covers the gearbox.
- Look over the chains or strap and the casters before each use.
FAQ: garage tools
What capacity transmission jack do I need for a diesel truck?
Match the rated capacity to the gearbox: the 1100 lb listings here suit heavier gearboxes, while the 450 lb listings suit lighter car and light truck gearboxes. The TUFFIOM adapter also states it is not intended for semi-tractor sized trucks, so medium or light duty trucks are its limit.
Can a transmission jack adapter replace a full transmission jack?
It can, if the garage already has a floor jack with a removable saddle shaft. The labwork adapter fits 1-5/32 in saddle shafts and the TUFFIOM adapter fits 1-1/5 in saddle shafts. An adapter adds no lift of its own, so the floor jack sets the range.
How high should a transmission jack lift?
High enough to clear the frame with the truck on stands. The VEVOR lifts from 33.5 to 67 in, and the low profile jacks lift from 7 to 23 in. Measure the truck on stands before choosing.
Do I need safety chains on a transmission jack?
Chains or a strap hold the gearbox on the saddle while it moves. The VEVOR and TUFFIOM picks include chains, and the Maxsa and Garvee picks include a nylon safety strap. The labwork adapter lists no safety feature, so the gearbox rests on the saddle alone.
