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.

    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.

    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.
