The plastic OE torque converter clutch solenoid snouts are prone to breakage, causing them to leak oil that should be directed to the converter clutch apply valve. Until now, your only option was to replace the entire OE harness or purchase an aftermarket solenoid and splice it into the existing harness. Sonnax solenoid snout 77942-01K allows the OE solenoid in '96-earlier 4L60/E units to be rebuilt to better-than-new condition. Sonnax also offers TCC solenoid snout 77942-02K that eliminates the need for the damage-prone plastic OE drainback valve in for ‘97-later PWM units.
