A friend of mine has a '93 TBird with a tranny problem. He has checked with a couple of local shops and they tell him it has to be rebuilt. I told him I would get some second opinions from you guys. So, here is the problem:

When the tranny is in Overdrive it slips out of OD at around 40mph. One shop told him a valve needed replaced but the entire tranny would have to be rebuilt to do so. Does anyone have any thoughts as to the possible problem and a solution?

Any and all help is appreciated.
Thanks,
Jeremy

I don't use the overdrive in my truck till I get up to 50mph.The mechanics at 2 different shop and they told me not to use the overdrive below 50mph.

Jeremy,what do you mean by,"slips out at 40 mph"? That is the speed{37-40} that the overdrive is supposed to engage. Is it hunting in and out? If so,you probably just need to speed up,out of the shift range. Driving around with the trans in OD won't hurt anything,unless you are shifting in and out alot,or towing,or steep grades. Heat is the enemy of automatics.
