THE CORRECT ANSWER DEPENDS ON THE MAKE AND YEAR OF THE CAR... IN SOME CASES LIKE FOR EXAMPLE, CHRYSLER HAS A DISK WITH 3 GEARS. THESE GEARS BRAKE.. YOU WILL HEAR A CRIMPING SOUND AND NO REVERSE. ALONG WITH THIS ALL THE METAL PARTICLES WILL DAMAGE YOUR CLUTCHES AND ALL THE CLUTCHES ON YOUR DRUMS WILL HAVE TO BE REPLACED. ON OTHER CARS COULD BE YOUR CONTROL MODULE, OR A SENSOR RELATED THAT SENDS A SIGNAL TO YOUR CONTROL SELENOID. SPEED SENSOR, ON SOME CARS. KNOCK SENSOR AND TPS SENSOR. GOOD LUCK
