Transmission Valve
Bodies
The transmission valve body is the brain
of the transmission. Often it is called the control valve. The
valve body, like the transmission, has been changed and updated through
the years. We select and use only the valve body that will provide you
with the best performance and service. All TCI® valve bodies are 100%
quality checked for proper function and, where applicable, proper
operating pressures on a dedicated valve body test machine.
We offer three types of modified valve
bodies.
StreetFighter®
Series - Manual/Automatic
Our
manual/automatic valve body is designed for the street and strip
performance car owner. It is the same valve body used in our StreetFighter®
transmission series.

Full Manual
Series
 Our
competition valve body for maximum performance and quick elapsed
times in a racing application. By controlling the valve body
only through manual means we can produce quicker shift timing
and are able to run higher line pressures than possible with an
automatic shift transmission. Higher line pressure makes it
harder for clutches to slip under high loads. Remember, with a
full manual you will have to make every shift, for these units
do not shift on their own. A great choice for bracket cars,
monster trucks, and virtually any off-road competition vehicle
where a Trans-Brake is either not legal or not desired.

| TCI® Full Manual Valve Body With Engine Braking For Turbo 400 |
 |
Making the right shift at the right time is critical to getting the most performance from your transmission. The new TCI® TH400 Full Manual Shift Valve Body with Low Gear Engine Braking is the best way to deliver quick shift response times and clean neutral shifting. Best of all, the full engine braking in low gear is perfect for rock crawling and 4x4 applications where utilizing the engine’s compression drag to help traverse the most extreme terrains is a useful feature.
The TCI® TH400 Full Manual Valve Body with Low Gear Engine Braking is the perfect set-up not only for heavy off road usage, but is great for hot street/strip cars where a forward shift pattern valve body ensures reliable transmission gear selection. As with all TCI® valve bodies, installation is a simple bolt-in procedure for any GM TH400 transmission with all necessary parts included and performance is guaranteed due to the rigorous TCI® quality control standards.

Trans-Brake Solenoids
 When
you come to the line to make that all-important run, the last thing you
should be thinking about is whether you purchased the best Trans-Brake
solenoid available. With the purchase of TCI®'s new Trans-Brake
solenoid, you'll know you have state-of-the-art engineering
incorporating such features as a precision-ground steel shaft with
bronze bushing, a shaft-pinned nut for secure placement and unique lip
seal to prevent fluid leakage while minimizing mechanical drag. The
TCI® solenoid motor is only 1.025-inches long, the most compact,
space-saving solenoid available. The conical-face design is able to
handle higher forces than standard flat-faced solenoids with 0.180 to
0.200-inch 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 assures a good quality ground can be established.
