My daughters 2001 impala went thru a stop sign and when she was speeding up the engine kept working but the car wouldn't go. Transmission. Also the battery was too dead to turn over this morning.
A good mechanic. In the meantime, I'd check the battery, remove nad take it over to your local auto parts store or drive it over, they can test for free. Then check the trans fluid, a low level will feel like it is neutral.
get the alternator tested...and it might have kinda stalled during the stop sign incident. the "kinda stalling" would of made the brakes harder to push to stop the car.
