This popular universal unit will allow you to put an electronic transmission behind any 6.2L or 6.5L diesel engine! Including mechanical and electronic injection pump engines.

Compatible with most popular GM transmissions, including the 4L60E, 4L65E, 4L80E and 4L85E, and the TCI® 6x Six-Speed Transmission. The EZ-TCU™ allows for maximum electronic control over shift points, shift firmness and shift speed. Self diagnostics allow users of every skill level to fully utilize the EZ-TCU™. The complete kit includes the transmission control unit, hand-held unit and wiring harness.

The EZ-TCU™ is fully configured and ready to run right out of the box – no tuning necessary. But for those who demand customization, the unit is also optionally fully programmable based on load, speed and rpm. TCI® and FAST™ engineers took a page from the very successful FAST™ EZ-EFI® Self Tuning Fuel Injection System and designed the EZ-TCU™ programming interface to be completely intuitive. There is no real expertise needed if you want to custom program your calibration. The EZ-TCU™ is capable of real-time switchable calibrations, which allows for multiple setups. Run one calibration for towing, and then with the push of a button, have a more aggressive setup for daily driving (example). The multiple shift modes include full manual mode for using bump or paddle shifters (sold separately).

This is an advanced user-tunable system which we do not provide assumed support with. Support will be billed in-advance, at hourly rates, with meetings scheduled accordingly. Don't let this scare you! It is one of the easiest systems on the market to configure with no laptop required!
