Why does my GMC Yukon come out of first gear?
At 2,430 miles, while in the Sierras outside Yosemite at 2500 feet, the transmission heated up to almost 200 degrees (outside temp only 78), and it came out of gear again. This time it would not shift out of first gear until we let it sit overnight. Drove it back to the dealer. Now they are talking about putting in a new transmission.
