While driving on a hilly highway at 55 mph, the truck suddenly lurched into an extreme downshift as I was going downhill. I had not been making any significant braking or acceleration motions--just driving normally with the flow of traffic and I had nothing in tow. The truck decelerated quickly and the rpms climbed significantly. This occurred twice: once around 2,800 miles and a second time at 3,400 miles, under the same conditions - dry roads, daytime, going downhill on a highway. There were not any warnings, and none of the service lights came on. It would not shift out of this gear. Each time, I had to avoid being hit from behind, and pulled over to the side of the road to stop completely. Then I was able to proceed with normal functioning of the transmission. The cause is unknown.
