The Sonnax TCC PWM (pulse width modulation) valve is a critical component in the GM 6T40/6T45/6T50 transmission. It is responsible for controlling the torque converter clutch (TCC) apply and release. The valve is located in the valve body and is actuated by the transmission control module (TCM).The TCC PWM valve is a critical component in the GM 6T40/6T45/6T50 transmission. It is responsible for controlling the torque converter clutch (TCC) apply and release. The valve is located in the valve body and is actuated by the transmission control module (TCM). The valve is a poppet-style valve that is actuated by a solenoid. The solenoid is controlled by the TCM and is used to regulate the amount of fluid pressure that is applied to the TCC. The valve is designed to open and close quickly, allowing for precise control of the TCC.The Sonnax TCC PWM valve is a direct replacement for the OE valve and is designed to provide improved performance and reliability. The valve is constructed from high-quality materials and is designed to withstand the high pressures and temperatures found in the transmission. The valve is also designed to provide improved shift quality and reduce the risk of TCC-related transmission issues.
