Purchased last month with 149,000 miles….driven about 2,000 miles some heavy towing but nothing out of the ordinary. Truck all of sudden will not shift out of first gear. No noise, no hard shifts prior to this. Check Engine light on. Visiting relatives and had to tow the truck to a dealer in a small town 3 hrs from home with very young technicians that do not have high ratings online. They said it needed a new transmission and would cost $9600.00 to replace. Is this common or should I tow to a reputable dealer near my home?
