Hi. I'm sure you've all seen this situation before and hopefully someone can come up with a solution.
I have a C200 2 litre auto W203. It had the issue when I bought the car.
I can get the lever to shift from park to drive. On engaginging it gives a good wallop, even when put in reverse. Start driving and it will not shift up and stays stuck in first.
Read codes on it and it came back as incorrect gear ratio plus tcm. Opened the sump and found the module in a bit of a state. So went out and bought a complete used gearbox from another exact model. Changed the module. Drove the car and it started to shift. However got in the following day to drive and back to square one:sad::sad::sad:. Read the code once again and came up with incorrect gear ratio . The tcm code has gone.
It will not shift manually either, nor will it switch between over into sports mode.
The oil and filter are fresh so I guess I can rule that out.
Anyone out there who knows what the problem is?
Solution will be more than appreciated.
Thanks
