Internal Control Powerglide Valve Body
The next generation in circle track valve bodies. The previous valve body simplified operation by eliminating the bulky hand-operated ball valve pressure control that was once so common, replacing it with a clutch-pedal control. Now you can free yourself of all external pressure controls, letting you concentrate on the competition instead! The TCI® 744500 & 744600 reverse pattern, full-manual valve bodys control line pressure internally and automatically. Put the car in gear and go! The reverse shift pattern allows up shifts without the worry of hitting neutral or reverse. It'll even operate smooth enough to allow you to drive on and off your trailer.

External Control Powerglide Valve Body
Our valve body eliminates the need for external valving of line pressure when using a straight pump drive. This full-manual Circle Track Valve Body can be easily installed. The design allows you to operate using the stock transmission detent linkage. Simply connect a clutch pedal to transmission detent lever supplied with kit. Depress the pedal, place the transmission in gear, ease the pedal out and the car moves. Forward Shift Pattern.

Your driveshaft is the critical link between your transmission and the rear end. The new TCI® 8-Inch X-Long Yoke for 27 Spline Transmissions avoids yoke “pull out” and “bottom out” which can lead to extreme transmission & rear end damage. This high-strength, forged steel construction yoke is designed to handle the extreme conditions found with high-end circle track racing drivetrains featuring the GM Powerglide, TH350, Brinn Transmissions and any other 27 spline output shaft transmission.

Electric Brake Shut-Off
Racers want every advantage possible. The new TCI® Electric Brake Shut-Off allows the driver to electrically shut-off the right front brake caliper to enhance corner entry handling in dirt, circle track racing applications. The easy-to-install solenoid mounts directly into the brake line, anywhere between the master cylinder and caliper. A flip of the switch from the inside of the car by the driver activates the lightweight 6061-T6 aluminum encased, continuous duty solenoid. This high-quality solenoid blocks fluid flow to the right front caliper, eliminating the common “push or tight” condition experienced under corner entry braking.

Adjustable Slip Collar for TCI® Two-Piece Direct Drives
This split ring collar will insure that your pump drive will stay engaged if the spiral lock breaks. Simply install the drive hub with the current spiral lock in place and the collar can be secured around the hub and locked into place with the two Allen bolts. Offered as an option for any of our two piece drives.

Max Shift™ Circle Track Transmission Fluid
TCI® Max Shift™ Circle Track Transmission Fluid offers several unique benefits to circle track racers over other fluids on the market, including anti-foaming agents that reduce pump cavitation for more consistent line pressures. Max Shift™ Circle Track also maintains an exceptionally high viscosity level at high temperatures, which increases the life of not only the fluid, but of the clutches and bands, as well. This makes the formula ideal for resistance against high temperature drivetrain wear, as well as fluid breakdown that is common in most high performance circle track racing applications. In addition, applications using a torque converter see minimized slippage, which translates into quicker acceleration on the straightaways.
