Product Details

The TCI Auto 221201 is a high-performance full manual valve body designed for GM TH400 automatic transmissions. This valve body features a reverse shift pattern configuration and delivers the manual control needed for racing and high-performance applications.

Key Features:

  • Full manual control for precise shift timing and improved performance
  • Reverse shift pattern configuration for race applications
  • Engine braking capability in 1st and 2nd gears for better control
  • Higher line pressures reduce clutch slippage under high load conditions
  • Quicker shift timing delivers more power to the ground
  • Direct replacement for GM TH400 transmissions

This valve body is engineered for bracket racing cars, monster trucks, and off-road competition vehicles where a transbrake is either illegal or undesirable. The full manual design eliminates automatic shifting, giving the driver complete control over gear selection while maximizing transmission performance and durability under demanding conditions.
