2006 Pontiac Grand Prix Will not register that it is in park, neutral, 3rd gear or 1st gear on the tree.
Because it will not registar every other slot on the gear shift and it will not register that it is in park it will not allow me to start the car.
Like an MLP sensor ? manual lever position. tr sensor? trans range Use google for your year, make, model and symptom. Read your codes. there are sites for that . like enginecodes .com. possible causes definition, etc. There has been issues with that make and some applications I have read that were similar. actuating the gearshift back and forth can get it to respond to get out of where it stalled sometimes?
