Hey- I am looking for a shift selector for a 1997 gulfstream tourmaster class a. We purchased this unit used and have found this shift selector to be bad. The number on it is 29523012. I believe it is the whole assembly. I'm guessing it is for the allison transmission which the md3060 stands for. Any help would be greatly appreciated. Does anyone know maybe what I would need???? Thanks for any help out there.
