High TCC apply pressures in the listed Chrysler units cause the TCC (lockup piston) to deflect or balloon. This occurs because of insufficient control of apply and release oil circuits. This apply pressure spike causes a chain reaction of events. The TCC deflection causes converter failure, sending TCC friction lining material through the transmission. This can restrict the radiator, cause lack of lube, planetary meltdown or total unit failure. Often the unit may be overhauled and a repeat planetary failure could result from an undetected restricted cooler. Other complaints are converter shudder, or TCC lockup surge between 35 to 40 mph. The redesigned Sonnax TCC control and plunger valve kit 92835-03K regulates TCC apply and release oil.

Valve kit is compatible with all controllers
Control valve is designed with an undersized middle spool that acts like an orifice to control flow entering the converter
Once flow passes through the middle spool, apply pressure is controlled by the internally regulated control plunger
