This wear allows pressure loss and 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. In 41 and 42 series units, TCC concerns can result, including engine stalling due to improper lockup. Installing patented Sonnax solenoid switch valve plug kit 92835-02K restores normal operation and control to this circuit. Patented Sonnax plugs redesigned to prevent cocking Annular grooves help center plugs in bore to prevent future side-load wear Contents: Inner Plug Outer Plug
