Turbo 400 TH400 Reverse Shift Pattern Full Manual Valve Body w/ 1st and 2nd Gear Engine Braking.

Full Manual TH400 Valve Body that has 1st and 2nd gear engine braking. This Turbo 400 Valve body is Reverse Shift Pattern.

New full T400 manual valve body from TCI® allows for quicker, more positive shifting & includes engine braking to assist with deceleration in rock crawlers & 4x4 vehicles

Four-wheel drive vehicles tend to be tough on drivetrain components, especially the applications that are intended for more serious use. To counter this ongoing dilemma, engineers at TCI have designed a Full Manual Reverse Shift Pattern Valve Body with an engine braking function for GM Turbo 400 transmissions. The innovative TCI engine braking system not only improves deceleration, it also aides the braking system of the vehicle.

In addition to engine braking, this revolutionary TH400 valve body from TCI has several other unique benefits. Its full manual shifting allows the operator of the vehicle to select gears manually, which allows for quicker shift timing and higher line pressures that reduce clutch slippage under high loads. In addition, the valve body’s reverse shift pattern makes for a better fit with many GM off-road performance applications.

All TCI® valve bodies are 100% quality checked for proper function and, where applicable, proper operating pressures are checked on a highly accurate valve body testing machine.
