(Figure 1)
A new torque converter clutch (TCC) solenoid, which has an internal rubber seal that will prevent sediment from sticking to the electromagnetic portion
of the solenoid, is in production in all 1987 THM 125C models built after Julian date 160. The new solenoid will reduce the potential of TCC Solenoid
sticking and the resulting condition of the engine stalling while shifting into reverse or drive.
