Please check your new transmission control system contents. You should have received the following items:
This TCI® Transmission Control Unit (TCU) system is designed to be used with the following transmissions: Ford AODE/4R70W, Ford E4OD/4R100, GM 4L60E/4L65E and GM 4L80E/4L85E.
These transmissions are fully electronic and will not shift automatically with out a transmission control system connected to it. TCI's TCU, computer software and wiring harness enable the transmission to operate. The TCU is fully programmable; part throttle, Wide Open Throttle (WOT), shift firmness and speeds can be custom tailored to the application. The torque converter lock-up is also fully adjustable. All of the wiring harness wires are clearly labeled. You can refer to the wiring diagrams for more detail, but you should find that the system is set up as a 'plug-and-play' application.
