SonnaxValve Kit

Excessive clearance at the outboard spool fed by the PWM solenoid allows modulating lube to exhaust. The resulting pressure loss causes reduced TC lockup clutch apply pressure, creating TCC-related complaints. Bore wear at the inboard spool can contribute to reduced line pressure. The Sonnax kit 68942-10K salvages the valve body with an oversized hard-anodized valve and a custom spring. Oversized valve salvages valve bodies with worn TC lock-up clutch regulator valve bore. Kit restores normal converter charge and cooler flow. Valve design corrects harsh or no TCC apply, TCC slipping and burn-up.
