We pride ourselves on providing valve body designs that stand out from the competition. We build and design our own valve bodies in house and test all full manual and transbrake valve bodies on our valve body dyno before we ship. You can feel confident we have provided you with a properly working unit. All valve bodies are lapped to provide a flat mating surface to minimize cross leaks. We also use an Ultrasonic cleaning machine for the final wash before assembly. This ensures all tiny passages are free of debris. By designing our own valve bodies we know how they work and we can provide our customers with any vital information they may need to properly set up the transmission to work with our valve body.
