Update: Took it to mechanics, they setup a thing to bypass the switch and it started shifting really hard. They said to get the switch put on i'd need to take it to BMW since they don't have the tools. Friend said a tranmission service in town can remove and fix it. Took it to that transmission mechanic, he put range selector switch on but it is still hard shifting.

Transmission guy didn't charge me a cent but I guess I'm going for a trip to the closest dealer...good news is, the transmission guy removed the jimmy rigged thing and now has the range selector switch on
