Excellent tool

Easy to use

Arrived quickly, good price, did the job,

I like the ease of use. I dont like that the arms that push on the spring retainer are very loose and unstable.

Good and strong tool

I had a hard time screwing down the handle to press in a reverse clutch piston. The press is super weak. If you try hard to tighten it the screw eats into the press itself and leaves little metal shavings in the unit. I went ahead and spend the $350 on an actual foot press and I was happy with it. This press is not worth wasting the time it won’t do what you need it to do and you’ll spend more money in the long run.

Works great on clutches with shafts like 4R70W/AOD/E forward drum.

The cross bar that the "feet" hang on was welded crooked to the all thread so one foot contacts before the other. managed to make it work, but was fighting it the whole time.

So this press does work with a little a little thought. The material is very thin and meant for light duty springs for sure. Also the leg span is too close together, I 6L80 Input shaft or 456 shaft will not fit. you have to rig up a support to make this work. Leg span needs to be wider to allow the input diameter to fit.

It’s cheap. It doesn’t really fit, needs to by files a bit but does the job

The part that compresses the retainer plate was incorrect and I had to modify it to give clearance to get the c clip that holds the plate into position.
