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.

    check engine light came on. mechanic thought transmission may need to be replaced but after examining the car, found that it was torque selinoid. I picked up car, and light came on again. This time I was told it was a manifold vacuum.
