Solenoid switch valve plugs in Chrysler 41TE, 42LE, 62TE and 68RFE families of transmissions cause bore wear as they oscillate and stroke during operation.
This wear allows pressure loss, cross-leakage and often permits the plugs to cock and hang up in the bore. This can result in failsafe mode, various codes, bind-ups and burnt 4th or overdrive clutches. Installing patented Sonnax solenoid switch valve plug kit 92835-39K restores normal operation and control to this circuit.
