TransGo SHIFT KIT® Valve Body Repair Kit for 6T30, 6T40, 6T45 (2007-2012)
Product Overview:
This TransGo SHIFT KIT® Valve Body Repair Kit is designed for 2007 to 2012 General Motors vehicles equipped with GEN1 6T30, 6T40, and 6T45 automatic transmissions. These transmissions often experience issues such as soft or flared shifts, burned friction plates, TCC slip, and various solenoid and gear ratio codes. Please note, this kit is not compatible with GEN2 units.
Common Issues Addressed:
The primary cause of these issues is often wear in the actuator feed limit (AFL) valve. The AFL valve's role is to regulate the pressure supplied to the solenoids, ensuring it does not exceed a set PSI, regardless of the main line pressure. This regulation is crucial to prevent overfeeding or underfeeding the solenoids, which can lead to poor shift quality and related error codes due to improper line pressure.
Another source of these problems is wear at the spring end of the pressure regulator valve or its bore, which affects the EPC boost signal. When wear occurs, it results in slow pressure boost response, low line pressure, clutch slippage, and additional solenoid and gear ratio issues. Additionally, wear in the TCC regulator valve bore can lead to TCC slip and corresponding error codes.
Features and Benefits:
- Includes a new drop-in AFL valve system with a bushing, valve, spring, spacer, and retainer to restore proper AFL function, even in worn bores.
- The TCC regulator valve features a drop-in hardened steel design with repositioned longer lands and a scarf cut sealing ring, allowing it to seal effectively in the original worn bore.
- A newly designed PR valve with longer lands restores the function and reliability of the pressure regulation system.
- Kit includes new O-rings and diaphragms to renew the TEHCM pressure switches, ensuring reliable operation.
