Car won't shift out of 1st gear

Do you know what kit they are going to replace? I'm curious. Good Luck, I hope that works!

I have the same thing going on with my mercedes s430 its a shift module celenoid. Mercedes quoted me costing me no more then $1000.00 it's not transmission don't take your mercedes to a local mechanic no matter how good they are. They wont have the diagnostic equipment to fix it. Mercedes don't have shift lock systems on their shifters. My understanding is this is a common problem. I hope this gives you some info to go about your problem. I couldn't find any information regarding this issue online either. Good Luck.
