Allison 1000 / 2000 / 2400 6-Speed TransGo Shift Kit, 2005-2010, SK Allison-Jr.
This TransGo Allison-Jr Shift Kit Valve Body Repair Kit fits 2005 to 2010 General Motors vehicles equipped with the Allison 1000, 2000 and 2400 six-speed automatic transmission.
Common complaints include neutralizing under heavy load in 4th or 5th, stuck in one gear, as well as gear ratio and solenoid performance codes.
Additionally, the valve body components provide substantial gains in friction plate durability. With this kit installed, the friction torque capacity of the holding clutches and brakes in 2nd through 6th gear is increased by approximately 100% when the lock-up clutch is off and line pressure is at maximum. However, transmission removal is not required. Install before adding engine horsepower to prevent internal damage.
