Transmission problem with my 2002 Pontiac Grand prix gt
3.8
tech = sf
question = I OWN A 2002 GRAND PRIX NO SUPERCHARGER 3.8 MOTOR AUTO
TRANS. I RECENTLY LOST 4TH GEAR NOW IT FEELS LIKE THE TRANNY IS
ABOUT TO GO COMPLETELY. I WANT TO REBUILD IT BUT AM UNSURE
ABOUT WHAT PARTS I WOULD NEED TO BUY ALONG WITH A REBUILD KIT TO
GET ALL THE UPDATED PARTS
SF:
It would be impossible to say what more parts you would need. No telling what has
failed. Removal of the pan can give an indication if there is metal throuought. If
so, may be cheaper to get a replacement unit. The final drive may have failed.
An overhaul kit from GM will have all updated seals, plates, valve body spacer,
etc.

Answer: The only way to remove the transmission from your vehicle is to
drop the subframe out of the car. You will need a proper engine support
fixture to carry the weight of the engine and transmission once the
subframe is removed, to keep it in place. You'd also have to either
remove the steering rack with the subframe or leave it hang in the car.
Just be sure the intermediate shaft does not come off if you lower the
frame/rack too much. Ball joints will have to be disconnected, frame bolts,
any harnesses and lines connected to the subframe will have to be
removed, etc. Not a difficult job, just lots of odds and ends.

Answer: There could be several reasons for this problem. It would depend
on if there is any engine codes being set in the computer with the check
engine light on. These can effect transmission operation. If no engine light,
there still may trans codes stored as some do not turn on the light. For
causes, it could any number of internal problems- Torque converter clutch
PMV solenoid, 2-3 shift solenoid, sticking valve in the valvebody, a piston
seal that is not seating, etc. Have a trans. Technician drive it first so he can
determine for a fact it is internal. It may need to come out and disassemble.
