About Getrag DC4 tuning

The Getrag DC4 transmission control unit is supported in 2 models from Renault. We read, modify, and flash it with AutoTuner, then verify the result on our Dynojet 424xLC2 in Jenison, MI. Transmission tuning sharpens shift timing, firmness, and torque limits to match your power.
