I was driving on the highway at highway speed when I thought I was rear-ended. I checked my mirrors and no other drivers were near me. As I was trying to process what happened I felt the jolt again. I stopped and checked for any clues to what had happened. I didn't see any leaks or signs of trouble. I decided to drive the car back to my house just a few miles away. On the way home at about 40-50 mph an AT light came on next to the dash gear indicator and the gear indicator got stuck on 3. By the time I got home the car was smoking but not overheated there was transmission oil that had overflowed out of the tranny dip stick tube.

My car has an automatic transmission.
Hi. This is a good indication that the transmission has overheated and damaged a lot of the internal parts of the transmission. This could have been caused by low transmission fluid or extremely dirty transmission fluid causing a cloth in the transmission. Your transmission will need to be rebuilt or replaced with a new one to fix this problem. I suggest you take your car to a local transmission shop to get it repaired. Unfortunately, here at YourMechanic we do not replace transmission. We could offer a second opinion by having these symptoms diagnosed by one of our mobile technicians in order to confirm my suspicions and suggest an accurate repair. Best of luck.
