When I started the car this morning, I heard a high-pitched grinding noise - something I've never heard before. Driving at 30mph, the car suddenly accelerated as I applied the brakes rounding a corner. I could hear the engine revving up so I quickly shifted it into neutral until it went back to normal. Then shifted it into drive and continued on.
