2006 G Wagon Shifting Module Question!

Hello,

I'm dumb:shakehead..I've spilt a coffee on the shifter module on my G Wagon. It drives, but does not go into any other gear.

Two questions: Is this hard to replace and location? Where do i get this part other than the dealer?

Any help our opinion will be helpful

B-

I know you have it fixed by now but this is for others looking at the post. Water on the shifter is BAD. It almost always requires replacement after a swim, this can only be done at a shop with scan tools that can perform computer programing. Sorry, it's going to cost you.
