Automatic Cold Weather Fix! (neutral safety switch can't shift out of park key stuck)

Is it neutal safty switch or
“If the TP sensor is at fault, replace the throttle body.”

Guyz, now I’m really confused. Tonight its gonna be 33F. I just waited in my car for 2 minutes until the “P” light turned on. Its getting worst as its getting colder. I was gonna be late for my class today.
How much is it going to cost? One more thing. I live in a small town, mechanics here have never seen a fancy car like ours :bang:
What am I suppose to tell them? I don’t wanna get ripped off by some Asshole. :worry:

Thanks for the helps Though
