I had the same problem with my 98 at 170,000 plus miles. I drove it home from a trip and several more days with no problems. Just think about it: 5th is really overdrive and most cars in the past did not even have overdrive. I chose to have the upgraded nut from Mopar put on and it works just great. I figured that if the old one lasted 170,000 miles, I should get even greater mileage from the improved version.
