Custom TCU Tune
$250.00
A great engine tune deserves a transmission calibration to match, and our Custom TCU Tune is built to make your gearbox work with your power, not against it. We optimize shift points, shift speed and firmness, torque limiters, and clutch and line pressures to deliver quicker, crisper, more decisive shifts while protecting the transmission's longevity. Every calibration is developed on the road and verified on the dyno against manufacturer spec sheets. Send us your vehicle and transmission details along with your engine setup through our Controller ID process and we will tailor the TCU file to your exact combination. The following TCU's are currently supported for tuning.
- AL420 (0CK)
- AL450 (0D9)
- AL551 (0C8)
- AL552 (0D5)
- AL651 (0BK)
- AL991 (0D0)
- AQ250 (09G)
- AQ450 (09M)
- DL382 (0CK / 0CJ)
- DL501 (0B5)
- DL800 (0D1)
- DQ200 (0AM / 0BM)
- DQ250 (02E / 0D9)
- DQ380 (0DE)

Stock, the transmission is written to be invisible. It upshifts early, downshifts late, and cuts torque so the box stays comfortable. You feel a car that will not hold a gear when you want it. We rewrite shift schedule, firmness, and how much torque the box will actually pass. Gears hold when you are in it, downshifts come when you ask, and the car puts the engine’s power down instead of folding up in the middle of a pull.
If your car is in this table, this is the file.
