This information is not for the typical performance aftermarket customer.

The information on this page is targeted for the engineer or software developer who requires direct, custom access to the transmission controller. Due to the fact that the PCS transmission controller is the most versatile and robust automatic transmission controller on the market, we receive numerous requests from OEM's that are developing a new powertrain, building a prototype for proof-of-concept evaluation, or implementing our controller in a test environment which requires integration with other preexisting control subsystems. The hardware is so versatile, customers have actually used it to perform other tasks besides transmission control.

We believe this documentation to provide all the necessary information to directly access the functionality of the transmission controller. If you require additional information, please do not hesitate to contact our engineering team.

Disclaimer
Information provided in this documentation allows for direct access to the transmission controller and transmission. When the controller is accessed in this manner, there are no safeguards in place to prevent instant catastrophic failure of the transmission and/or vehicle.
