For 2 weeks the truck felt like it was hesitating somewhat when accelerating. Then when driving home on dry pavement one night, a pop sound was heard & second gear was gone.

You either rebuild it for $1600 with a new sun gear, or replace the tranny for $2600.

While traveling at 70 mph, vehicle started to down shift and the driver came to a stop, once going up a hill the vehicle started to lose power, driver pressed gas pedal, and there was no response, then suddenly vehicle took off. . Consumer stated when she stopped to make a turn, the vehicle would not move up the hill, and the accelerator pedal was to the floor, once the vehicle was put into low gear it moved.
