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

TCI 321115 Full Manual, Reverse Shift Pattern TH350 Valve Body with Full Engine BrakingOur 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 New Item!

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 Series

Our Trans-Brake 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 Trans-Brake action which prevents an engine's torque load from being transmitted through the drive train prior to the launch. The Trans-Brake acts in much the same manner as a manual clutch. Once the Trans-Brake 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 Trans-Brake 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.

Aluminum Powerglide Valve Bodies

These Trans-brake Series valve bodies allow you to achieve maximum torque converter stall and provide quicker, more consistent reaction times and 60-foot times.
628253 aluminum Powerglide valve body
These new kits offer exciting features like:
Reduced weight - 5 lbs. lighter than OEM cast iron valve body.
High Flow filter - reduces strain on pump
Redesigned pump inlet for reduced cavitation
CNC-machined to exacting tolerances for better sealing against leaks.

Trans-Brake Solenoids

TCI 749800 Powerglide Trans-Brake SolenoidWhen 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.
