The torque converter clutch (TTC) may stop working due to an internal transmission failure. The Check Engine Light will illuminate if this occurs. Our technicians tell us the transmission will require dis-assembly to correct this concern.

Also had TCC fault. Had service manual and was attempting to do a test on the 6-8 wire round electrical connector to the transmission. Near top of transmission but not too easy to see or get to. I got connector loose and tried to test, then gave up for awhile and reconnected. But this caused TCC fault to go away! Yes higher gas mileage returned! I think the connector had developed a bad connection on some of the terminals. I took connector off again later and dabbed a little terminal grease on each prong and never had a re-occurrence. This is a good maintenance technique for any connection you work with on an older car.
Check Engine Light was on when I bought the car, Had Autozone check it and it read P0741 and P1860, Tork Converter !!! Not sure what to do at this point !
I have driven the car for almost 10,000 miles so far and have had No problems with the Trans, Should I still be concerned ? Is it possible its something else causing this check engine light to stay on ? Maybe a sensor ??
