- Gaskets are not needed between the valve body and plates; requires the use of a deep pan for transbrake solenoid clearance.
FAQ
What does an upgraded valve body do?
- Enhances shifting performance
- Improves transmission durability
- Optimizes fluid flow for efficiency
How does a TH400 transbrake work?
- An electric solenoid engages with a press of a button and locks the transmission between low gear and reverse at the same time. This locks the vehicle stationary and allows you to rev your engine against the torque converter and release the button for a quick launch.
- Allows for precise control during drag racing
- Enhances reaction time for competitive advantage
What is the point of a manual valve body?
- Gives the driver full control over gear selection
- Eliminates automatic shifting for manual operation
- Ideal for racing applications requiring precise gear changes

Maximum Torque Converter Stall for Quick, Consistent Reaction Times

When JEGS Trans-Brake is engaged, the automatic transmission thinks it is in both first and reverse gear at the same time, so your vehicle cannot roll forward nor backward. This allows the engine to rev as high as the torque converter stall, so once the brake is released, power is immediately transferred to the rear tires, and you're at the finish line! JEGS Trans-Brake Valve Body Kits are complete with hardware and ready to install.
