Heavy duty transmission jack

[Frank S]

Finally put the jack to work
The truck came in that I built the transmission jack for.
the first thing I did set up my ramps to back the truck on.
A lot of guys pulling transmissions out of trucks will just raise the front end so they can have some room to work This is problematic as the engine and transmissions are mounted at a down slope angle if the front is higher than the rear the angle increases When pulling a transmission that weighs over 1000 lbs or any transmission for that matter the closer to having the engine and transmission parallel to the floor the better this makes for ease of removal and reassembly. since the jack only has to roll and not be adjusted for height as you are doing the job

It helps to have a lot of heavy duty large wood blocks

I have more if needed LOL

Back the truck up the ramps

Secure in place

Font is 10" off the ground and the rear is 18" the work floor under the truck is 2 4x8 sheets of 3/4 treated plywood

Transmission out on the jack. It works like a charm was able to raise the transmission and the rear of the engine with it to lift above the rear mounts and add a support under the engine to hold it in place was probably having to lift at least 4000 lbs


Due to there being a PTO mounted on the bottom of the transmission adjusting bolts were out of the question So I used my next favorite way of supporting things. Solid oak blocks then the transmission was strapped to the jack so it couldn't move
