The client's experimental vehicle technology test platform consists of modular drive train components. DMC's solution allows the client to run tests with automatic gear shifts on manual transmissions.  The servo system receives a binary code from the master test controller indicating the desired gear.  The servo system then actuates a clutch and uses two axis motion to shift to the appropriate gear.  The current status of the servo system and current gear is transmitted back to the master test controller.
