Default 4l60e low-reverse piston removal

Hi all...the LR piston in my '95 tranny won't pop loose using compressed air, not even with the regulator set at 90lbs! Any other way to remove the LR piston? Air seems to escape around the piston...and its 'loose' in its place and can be turned easily enough...that normal? I couldn't find any direction via the search feature...maybe I didn't look hard enuff. Thanks for any helps b'ys!

Low/reverse clutches are trashed bad. Everything else looks fine so far. This is a Goodwrench reman transmission.

Jake

Did you remove the parking pawl bracket so the parking pawl will swing out of the way?

If the park pawl is out of the way like jays said, use two long needle nose pliers, grab the outside rim that is sticking up at about the 1 and 7 o'clock positions...and gently and evenly pull up.

Oh also...if you don't have the spring retainer out...take it out. I assumed you had it out but...ya never know I guess

Thanks for the replies guys....the spring retainer is out, but I'd best be checking on the parking pawl bracket! Thanks again! Jake

you shouldnt be able to turn it, it has a tab and a notch. unless you have it out far enough past that. I think the parking lock is in the way. you need to take the parking mechanism out to get the piston out. Once you do that, you may need to slam the case down (not real hard, start out soft) on carpet, rubber mat, door mat....etc. itll fall out.

I've never had to take the park pawl out to get the low/rev piston out. you have to pivot it out of the way, but that's it.

Thanks for the replies...I went with the two needle-nose pliers and carefully pulled it out! Looks fine...some very light scratches on the side of the piston but that's all. Jake

As long as there aren't any scratches on the case where the lip seal goes...it should be just fine
