I was driving and the car overdrive light started blinking and then I went to drive and it started to and cut off when it jolted like someone hit me and my passenger from the rear but it was the gear or transmission or the overdrive not engaging, not sure. I sat there for about 5 minutes in neutral and then put the car in drive and it moved forward. After I parked the car it repeated the above action.
