Electronically controlled automatic transmissions offer tremendous tuning pssibilities and features, but only if you have the right hardware and software to make them sing. In this episode, we install a Transmission Control Unit (TCU) from TCI and set it up with TCI's T-COM 2 software. Once we installed the TCU in the car, we used a kit from Shiftworks to adapt our original GTO 2-speed console shifter to work with the new 4L65E electronic 4-speed automatic.
