 | | TCI® Valve Bodies | Full-Manual | |
|
The competition valve body was designed for maximum performance and quick elapsed times in racing applications. By controlling the valve body only through manual means, quicker shift timing and the ability to run higher line pressures than possible with an automatic shift transmission are achieved. Higher line pressure makes it more difficult for clutches to slip under high loads. TCI® Full Manual Valve Bodies are an excellent choice for bracket cars, monster trucks and virtually any off-road competition vehicle where a transbrake is either not legal or not desired.

Notes
- 1 - Use TCI® #146901 4.2 ratio lever
- 2 - Retains 2nd gear engine braking
- 3 - Retains 1st and 2nd gear engine braking
- 4 - Retains lock-up capability
 | | TCI® Valve Bodies | Trans-Brake | |
|
- Transbrake action prevents torque load transmission through drivetrain before launch
- Vehicle will not be able to roll forward or backward
- Power is transferred to rear tires, much like a manual clutch
|
| Our Transbrake Series allows you to achieve maximum torque converter stall and provides for quicker and more consistent reaction times and 60-foot times. This is due to the transbrake action which prevents an engine's torque load from being transmitted through the drivetrain prior to launch. The transbrake acts in much the same manner as a manual clutch. Once it is engaged, the vehicle can neither roll forward nor backward, and as you press on the accelerator, the engine can rpm as high as the torque converter stall. Once the transbrake is released, the power is transmitted immediately to the rear tires in much the same manner as a manual clutch but with the parts saving advantage of the torque converter's shock absorbing action. |
Trans-Brake Solenoids
The TCI® solenoid motor is only 1.025" long, the most compact, space-saving solenoid available. The conical face design is able to handle higher forces than standard flat-faced solenoids with .180 to .200" strokes. The high-efficiency, precision wound coil maximizes the amount of copper in the allowable space for maximum force and the two-wire set-up ensures a good quality ground can be established.
- Features precision-ground steel shaft with bronze bushing, shaft-pinned nut and unique lip seal to prevent fluid leakage
- Shaft-pinned nut for secure placement
- Unique lip seal to prevent fluid leakage while minimizing mechanical drag
