This Transmission is suitable for applications to 500+ hp, and bolts to The Chevrolet, Buick, Pontiac and Cadillac (or BOP pattern engines).

Its features include the following components and modifications (Nothing but the best):

GMCars051. High Performance rebuild kit with additional frictions where possible Frictions are Alto, Raybestos and Allomatic performance. Special attention is given to the direct 3rd clutch.

2. A hardened sun shell is installed, eliminating the weak area of the transmission. We also replace the factory plastic thrust washer with a brass one, eliminating melt down and breakage issues with this washer.

3. A wide red lining band, with reinforced band pin area is mated to a resurfaced drum for max hold.

4. A Superior Super Servo is used to assure adequate apply, and special modifications are done during installation to reduce the downshift clunk associated with these large servos. Between the wide band above and the super servo holding is increased up to 50 percent over stock in second gear.

5. A high performance pump with enlarged drain back, hardened pump rings, fixed position Pump slide( for max high rpm pressure), a .500 boost valve, and full time lube modification to the pressure regulator valve is used.

6. We use heavy duty front and rear sprags (one way roller clutch assemblies) to make sure this unit will take the torque.

7. We modified TCC apply to provide stronger engagement of the lockup clutch, and to enhance the increased durability of the higher (3000 up) stall torque converters if used. This modification also improves the life of any stall converter from stock up.

8. These transmissions have a PerformaBuilt Performance shift kit installed, and will have very positive shifts, which become progressively more aggressive as throttle is increased. No accumulators are blocked causing unnecessary strain in normal driving, but it still delivers that kick ass feel under throttle.

This unit also features many other modifications for performance and durability, helping it achieve its 500 plus horsepower capabilities. This transmission will take whatever you can dish out and we guarantee it! You won't find a better unit anywhere. And, with our customer service and the staying power that come with a larger company you can count on us to be there when you need us.
