Gear problems

[Nik.zour]

One quick question:
I gave my car (mercedes compressor 200) for washing, inside out, and after that, NO GEAR WORKS. I can only use the first gear...
Any idea how i could fix it??

Can you give a better description, washed inside and out, was a high pressure hose used, and in the engine bay?

1St gear works, what happens when it should shift to 2nd,what happens if you manually force a gear change

Either water or detergent has gotten into the selector module or the main battery has gone down chucking it into limp mode.
