So, i need to take the car to the shop. I just moved to Miami FL and i need a good place to take it to.

when driving "Normal" speeds its fine. I dont have a problem. when going above 82+ mph all of a sudden a HUGE thump sound the car makes and it feels like i got from the back of the car???? then the car studders once i lower the speed.

The dash then says (i think b/c some of the crystals dont show) Transmission re-prog??

thanks!
