'94 Lumina APV

I have a 1994 Chevy Lumina van, it has a V6 3.8, possibly a
4T60E transmission. The problem is the motor starts you put it in drive, the transmission hits hard and the motor dies. This only happens in OD, 1, 2, or 3. In park, neutral and reverse everything is fine, motor runs and will even drive in reverse, but as soon as you put it in drive, any gear, the transmission hits and the motor dies. I have put the car on jacks with the front wheels off the ground with the motor running and put it in drive, the motor does not die, but the front wheels spin rapidly leaving me to believe I am stuck in overdrive. I have unplugged the 2 different plugs that are on the side of the transmission, one on the front and one on the back end which I believe is the gear selector switch and it still had the problem. Could this possibly be TCC or is it another problem? If so, what can I do myself or do I need to take it a shop?

Sounds like the torque convertor clutch solenoid is stuck.

library/ chilton. parts store, chilton. if possible, do not buy haynes, descriptions are often wrong, directions are often wrong. find one that has drawings and diagrams instead of pictures, as those are mostly poor quality and you'll be killing your eyes trying to figure them out.
i have golden rule: bought a used one - buy a book right away. 14 bucks of best investment ever.
i'd safely say - library and their chilton, as they have pro books in there. parts stores ones have very little info on trannies overhauls and repairs. i just went through my silverado chilton - all it has in the chapter is how to pull trannie out and some minor repairs.
you can always scope it off internet.

i, personally, love seafoam product, which transtune is. yours, unfortunately, might be so advanced that cleaning won't help. changing ATF regularly helps a lot.

PS if you buy your part at Autozone, they should give you Alldata printout on repairs, they have access to it.
