Transgo SHIFT KIT Valve Body Repair Kit for GEN1 6T70, 6T75 (2007-2013) The TransGo 6T70-A SHIFT KIT® Valve Body Repair Kit is specifically designed for 2007 to 2013 General Motors vehicles equipped with GEN1 6T70 and 6T75 automatic transmissions. This kit addresses common issues such as erratic shifting, TCC slip, and various solenoid performance and gear ratio error codes, and is not suitable for GEN2 models. Many of these issues stem from wear in the actuator feed limit (AFL) valve bore, which regulates pressure to the solenoids, ensuring it does not exceed a specific PSI regardless of the main line pressure. Wear in the TCC regulator valve bore and the pressure regulator (PR) valve and bore can also contribute to these problems. Features and Benefits: Incorporates a new drop-in AFL valve system to restore function using the existing worn bore. Includes a drop-in hardened steel TCC regulator valve with a re-positioned longer land and a scarf cut sealing ring for original bore sealing. Features a redesigned PR valve with extended lands for improved line PR system reliability. Introduces a new relief system to replace the OE isolator valve lineup, preventing damage from pressure overboost. Comes with new rubber grommets and diaphragms to renew the TEHCM pressure switches. Corrects/Prevents/Reduces: Erratic TCC behavior and overboost-related breakages. Transmission error codes including P0741, P0742, P0751, P0752, P0756, P0757, P0776, P0777, P0796, P0797, P0842, P0843, P0872, P0873, P0877, P0878, P0989, P0990, P2714, P2715, P2723, and P2724. Kit Includes: Drop-in USA-made hardened steel PR valve and spring. USA-made hardened steel AFL valve and drop-in steel AFL bushing. AFL valve spring, spacer, and retainer. Drop-in USA-made hardened steel TCC regulator valve with scarf cut sealing ring, spring, and O-ring. Drop-in pressure relief bushing, spring, ball, and retainer. TCC control valve spring and retainer. Five pressure switch diaphragms and rubber grommets.
