Thanks for the quick response Will_w202 and RichardM98.

Ok IM not making this up. Just called the owner of the E420 and he said this morning car woulden't shift out of first (limp mode second?). So now i have the opportunity to get this car for really cheap. I have to call him back and get specific codes it was throwing.

Thing is I definatly dont need more pretty german lawn ornaments. SO wondering if it would be worth it to fix TCM module (if thats it) if i can get car sub $1500 and cost estimates to do that with worse case senario prices.
