TCU reprogramming and transmission board repair
The TCU is the electronic control unit of the automatic transmission. When it fails, the transmission goes into limp mode or stops changing gears. We repair and reprogram the boards in our workshop and test them before fitting.
Which electronics we work with
From diagnostics to adaptation
TCU reprogramming
Writing the correct software and adapting the control unit to the vehicle, for new and used boards.
Circuit board repair
Fixing the fault on the transmission board itself, without buying a new control unit.
Testing on the computer
Checking sensors, valves and selector position before fitting to the vehicle.
Adaptation after fitting
Diagnostic transmission adaptation and a test drive.
Signs of a faulty TCU
If the vehicle can't be driven, we bring it in with our towing service from anywhere in Serbia.
- The transmission goes into limp mode and stays in one gear
- A transmission error or "Visit workshop" appears on the dashboard
- Jerking, delayed or harsh gear changes
- The transmission doesn't recognise the selector position (P, R, N, D)
