My 1995 Pontiac Transport transmission suddenly quit. It has a little driving power in reverse and 1st gear. All other gears and drive are gone!
I connected an AutoXray scanner and received a message P0740, which indicates a problem in the Torque Converter Clutch circuit. I'm not sure if this interprets as 'electrical' or 'hydraulic' circuit? The vehicle has 143000mi and the transmission fluid looks dirty brown/black and smells a little like plastic. Since there is a little power in 1st and rev, could it be a plugged filter or bad TCC solenoid? Are these hard to get at?
I appreciate any advice, thanks. |
