BH Genesis Sedan 5.0L – TCU Tune


SKU: BH5.0TCU Category:


TCU Tune

We offer TCU (Transmission Control Unit) tuning for the latest automatic (8-speed) and DCT transmissions. If you are looking to improve the sharpness and overall drivability of your transmission, then this might be something to consider in your tuning search! A TCU tune must be accompanied by an ECU tune due to the raised rev limiter. For those who get both the ECU and TCU tune, you can take full advantage of the fuel cut feature – allows you to hold any gear without the transmission automatically up-shifting or down-shifting in manual mode. You can enjoy the increased REV limit with the purchase of our TCU without your transmission automatically up-shifting!

Your TCU tune will be loaded onto an EXTRA OEM TCU specifically made for your car. If you would like to send in your existing TCU, that is also an option! When purchasing your ECU & TCU tune, please email us at with a list of any modifications done to your car and engine (if applicable).

All of our ECU and TCU tunes include shipping to you and can be shipped anywhere in the world!
