700r losing reverse as warms up

So I have a 700r in my 92 olds and after doing the trans I get reverse only when the trans is cold as it warms up I lose it, does anyone have any ideas what could be happening?

Ive nevr rebuilt a transmission before but ill try to help you. As oil warms up it gets thinner. It could be anything major to minor. Might be an aculator piston a worn servo. Worn out hard parts. I dont believe its a sprag cause if the sprag was bad it wouldnt move at all in reverse. I come more to saying its something with a valve or piston. I have a 4l60e that i just pulled out of my truck i dont like them too much cause they dont seem to last. Ive had it rebuilt at a reputable shop. Mine is basicly an over reworked 700r4 with an electronic valve body.

It could be a simple cheap snap ring. Usually its the less expensive part that causes a huge load of problems.

so i talked with a guy at a transmission place today about a checkball and retainer in the trans side that as far as i see in the book controls reverse exhaust i took it out cause tci told me to but the guy at the trans place said i should have left it in cause it wont control any function of the valve body so now im confused on who to believe ill try to get a psi gauge in the next couple of days its getting hard cause this trans is eating up every last dollar i make and ill let you know if it has low preasure i know the boost valve in the pump is good cause its a brand new one the tci valve body made me put in
