I think he killed it...

To bring everyone up to date...

'92 GXE, Auto. Approx 100K miles. Dad had dumped some seafoam into his tank and engine immediately started running like crap, plus trans would not shift into OD and had some funny shifting 1-2. He was in LA and drove it home to Vegas in 3rd gear. After he got home, he reported that it was slipping in 2nd and 3rd and still had no OD, and engine was running like crap. Fluid was really dark and burnt, so he did the drain/refill a few times until the fluid looked decent (using Dex III). Still slipping though. Even got desparate and used some Lucas in it with no change.

I went up 2 weeks ago and put in new injectors to fix the engine problem. Engine runs like a dream now. Disconnected the battery to allow the TCU to reset. Accellerating slowly the trans works fine, but as soon as you try to give it some power it slips in 2nd and 3rd - and it slips bad. Seems that when it is cold it will go into OD, but no OD at all after it warms up.

So, new trans time? I looked at OE Surplus and they have no more RE4F02A transmissions (I even called to verify). If it was my car, I'd go with a 5 speed conversion, but mom can't drive a manual.

Options? Not really interested in combing junkyards for one. Anyone have a source for a GOOD trans shop in either Vegas(where he lives) or Phoenix(where I live)?

The car is in excellent shape and we don't want to scrap it.

I'm open to all suggestions!
