Chevy 4T65E Transmission Sonnax TCC Regulated Apply Valve Kit Symptoms: Code 741 Gear ratio codes TCC slip Cause: Bore wear at the TCC apply valve allows regulated apply oil to exhaust. Correction: Sonnax design improvements aid durability and restore apply pressure to eliminate converter clutch slippage. The OE TCC regulated apply bore in GM 4T65-E units wears, causing TCC signal (PWM) oil and TCC regulated apply oil to leak. The leakage lowers the apply pressure, which causes the torque converter clutch to slip. The Sonnax TCC regulated apply valve kit 84754-34K addresses TCC slip, code 741 and occasional ratio codes. Valve is hardcoat anodized to reduce wear Valve has annular grooves to prevent side loading Wear-resistant sleeve is much more durable than the valve body casting and provides additional valve support NOTE: Sonnax Tool 84754-TL3 is required to install this part! It is recommended to check separator plate orifices in this area for contamination. Additionally, the TCC apply valve bore should be examined for wear with any TCC related concerns.
