Jim, I will check after the snow leaves the ground. My wife drives the car most of the time, I very rarely get to drive it, I use the toyota 4 runner most of the time, where abouts is the shift module located, just in case I have to change it?? is there a check for the module to see if it is bad or does it just go bad. How long does it take or supposed to take to shift when the auto is cold. Hey I really appreciate all of the help, The Mercedes it a great running and comfortable car, but parts are sure expensive to repair them, first one that I have owned, really do like it. Ben
