Sonnax 84754-43K 4T65E Transmission TCC Apply Valve Kit with Seal

Description: 4T65-E Transmission TCC Apply Valve Kit Part No. 84754-43KIn GM 4T65-E units, continuous oscillation of the converter apply valve in the cast-aluminum bore causes bore wear, particularly at the TCC signal valve spool closest to the solenoid. Wear in this area allows TCC signal oil to leak, which inhibits the valve from stroking to the lockup position. Due to the valve body casting design and oil flow, this valve is also subject to extreme side loading, which increases the wear rate. Early OE versions of this valve were made from non-anodized aluminum, and show significant wear marks. Hardcoat anodized aluminum valve with an expandable PTFE seal on the TCC signal valve spool provides a positive seal to ensure proper stroking of the valve The most inward Sonnax valve spool is almost 2.5 times longer then the OE spool, creating more valve-to-bore sealing area Greater sealing area combined with annular grooves allows the valve to stay centered in the bore and prevents side loading A replacement O-ring has been included for the OE end plug, to be used after inspecting the TCC regulated apply valve Note Always inspect the TCC regulated apply valve for wear. The O-ring in this kit should be used to replace the original end plug O-ring after inspection. Worn valves or bores can be repaired using the Sonnax TCC regulated apply valve and sleeve kit 84754-34K. Contents Valve PTFE Seals (2) 1 extra Spring O-Ring
