#5 of 7 Same problem.... by rollinpearls Apr 14, 2008 (2:10 pm)
I recently purchased a 2000 Lincoln LS V8 in December 2007. The car runs wonderful (cold), but as soon as it reached operating temperature and you are stopped at a stop sign or light, the engine begins to fumble and eventually stalls. This will only happen if the car is in gear (drive or reverse). The used car dealer I bought it from did have the PCU changed 2 days after the sale. This cured the problem for awhile, but the problem is back. The car was parked over the winter. I've called the dealer back but now says that 4 months later there nothing he can do(which I understand). But what may be the cause of the problem. I read on this site that the PCU is self-learning on these cars, if so, would not driving the vehicle allow the new PCU to adjust and learned the old problem?

Replying to: rollinpearls (Apr 14, 2008 2:10 pm) this problen could be a tcc solenoid problem in the transmission industry a restricted tcc solenoid would essentially cause the torque converter clutch to stay applied even if the brakes are pressed the tcc solenoid wont be able to exhaust enough fluid to release the tcc. it would be basically the same as a plugged up catalytic converter when cold it will run for a little while but performance gets worse as the car warms up. same principle for the tcc solenoid. Im not always right but that would be my approach to the problem if the car came to my shop   This respons was from a member named " fordfan 17" I haven't done it yet but when I do, I'll update.
