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.Google+

nothing wrong with transmission, light sometimes goes out only to return. transmission has been working well for the last 20000 miles but now I cant pass emissions tests and there is nothing wrong but the sensor.
Service engine light keeps coming on. Code indicates p0741 and p1860. I am being told transmission needs to be removed so the harness and solenoids can be repaired. there are no other symptoms or any problems so I am researching.

check engine light comes on and goes off. check out saqys torque converter. 1st time in jan they said I needed the transmission oil shanged done that the light went off now it is back on I had it checked and now thety say it is the torque converter. Very upsetting.
decoder reads a P0741 problem causing engine light to appear. Constantly returns if erased but have not had any problems with transmission or engine performance.
