I just dropped my car off to have some things that have TSBs taken care of. The dealership is telling me that the TSBs are not valid and that nothing is wrong with my car. On top of that i have an issue with downshifting into first; it just grinds the hell out of the gear no matter how fast or slow i am going. The only way i can downshift is from a dead stop. I am told it is that way from the factory. Is this true?
