it's probably just fine.
My Corvette did that and found it was due to the computer sensing one wheel slipping. Mine happened when I backed into a gravel driveway. It only did it that one time and I know how you feel. I'm sure this has probably happend on more then just our Mustangs but other cars as well. It probably will never happen to you again but if it does go back to the dealer. You want to keep the problem on file. Ya gotta love the computer glitches.
