Product Description
4T65E TCC Regulated Apply Valve Kit
Sonnax Part Number: 84754-34K
TOOLING REQUIRED
- 84754-TL3
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. Sonnax TCC regulated apply valve kit 84754-34K addresses TCC slip, code 741 and occasional ratio codes.
- Hardcoat anodized valve combats premature 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
It is recommended to check separator plate orifices for contamination. Additionally, the TCC apply valve bore should be examined for wear with any TCC related concerns.
