700-R trans squeal
My trans has a squeal when it is backing up ..if you give it the gas. It sounds has a hi-pitched..dry sound. it never does this,with the kar in reverse backing up slowly.Its only when you try to back up the kar abit faster ,It then starts the squealing sound. I had a guy put a input bearing in the trans, in the kar,years ago. Is this the right name for it. Its the pump bearing ,it has to be mounted just right before engaging the torque converter squarely. Hope this made sense i remember he thru out a shim and said it wasn't necessary. it gets quite loud, the more you give it the gas in reverse.what do you think?
i've never bothered to repair it cause i don't back up much. and don't drive the kar as much as i used too,> bob s Last edited by bsa_bob; 02-06-2013 at 03:04 PM.

The trans definitely has to come out and apart,sorry to say....if I didn't see a stripped pump stator shaft spline while removing the converter,it wouldn't suprise me if I found a worn out low-reverse sprag in there. If just a few of the springs in that sprag assembly are worn/broken, it loses some of it's holding power,which could produce a screeching sound, under load, that you mentioned.It could very well be in another area,but without having it apart on my bench,all I can give you is a hunch.

Sorry Bob,but I don't do any transmission repairs unless it was my unit to begin with.If I did,I would get blamed for anything that fails, unrelated to what I repaired, down the road.Been there,done that.I strictly do complete rebuilds.And I'm sure you can find someone reliable in the Detroit area to do that for ya....Thank you for the inquiry,though.
