I have a recently rebuilt 56 cast iron powerglide that shifts very hard. It shifts into high gear very harshly, with a decided clunk. Is there any adjustment for this, or does it have to come out? Is there any documentation on rebuilding these things?

Re: 56 powerglide shifting problem
There is some adjustment, the TV linkage and also the vacuum modulator both affect the shift. I would look first at the vacuum modulator, and or the vacuum hookup to the modulator for a "too hard" shift.Bill Clupper #618 -

Re: 56 powerglide bad news
Schultz Poor guy E-mailed me after I told him how to adjust his trans shifting problem and realized he has to remove it now to correct it. Who ever rebuilt it srewed up.There is nothing simpler then a PG cast or alum. to rebuild.If any one can remove one from a Corvette , then you can rebuild it. A kit is around $100.00 and a shop doing it can run around $2000.00 and up. If any one can use help I'm willing to try and help you. ROYComment
