I have a 2019 Ford Escape SE, 106, 426 miles as of current. Ford dealer quoted me $8500 for a new transmission. Check engine light is on. I still owe about $8700 on current loan and making payments. The car does start but doesn't drive. Can I roll over negative equity into new loan? Will it be wiser to trade in or sell vehicle as is? Need answers.
