Transgo - Shift Kit V/Repair Kit Allison 6-Speed 05-10

The TransGo Shift Kit V/Repair Kit is engineered to improve the functionality and longevity of Allison 6-speed automatic transmissions in 2005-2010 General Motors vehicles. This kit addresses common issues such as neutralizing under heavy load in 4th or 5th gear, burnt C2 and C3 friction plates, and gear ratio and solenoid performance codes. By increasing the friction torque capacity of the holding clutches and brakes in 2nd through 6th gear by approximately 100%, this kit ensures smoother and more reliable transmission performance. Installation is straightforward and does not require transmission removal, making it an ideal upgrade for vehicles before adding engine horsepower to prevent internal damage.
