TCI EZ-TCU automatic transmission controllers are fully configured right out of the box--no tuning is necessary. Simply install them with the included instructions and then start the systems by answering the simple setup wizard questions on the included hand-held unit. They're capable of real-time switchable calibrations, which allows for multiple setups. The multi-shift settings include a full manual mode for using bump or paddle shifters. The TCI EZ-TCU automatic transmission controllers allow for maximum electronic control over shift points, shift firmness, and shift speed. Self-diagnostics enable users of every skill level to fully utilize their capabilities. Be sure to match your particular transmission with the correct EZ-TCU controller, as some models are designed for pre-2009 applications ... and other models are for 2009 and later.
