Car is a 04 mach with auto trans. Car starts fine but idels at about 2,500 rpm and when you drive it will not shift out of first gear.
Dont know if it has anything to do with it but my girl drove the car through about a foot of water the other night. Car ran fine for 3 days after then today is when the problems started.
