A system for calibrating the fill times of clutches using a pressure transducer service tool includes attaching the tool to an electronic controller on the vehicle and the a clutch hydraulic fluid line, signaling the controller to calibrate the clutch, then removing the service tool. The tool is sequentially moved from one clutch hydraulic line to another to calibrate several clutches. A single service tool with several transducers and a means of switching between them may also be used. The process is automated and the controller signals the user when to make the various connections. The operator then signals the controller when the connections have been made and calibration commences automatically.
