Transmission down shifts multiple gears when I decelerate. The first occurrence happened at 70 mph causing a very hard deceleration and near loss of control of the truck. I have had three other like incidences at speeds between 45 and 70 mph. These happened on dry pavement and I was able to slow safely. Had this occurred on wet or snow covered roads, I have no doubt there would have been an accident. 2. at times when I accelerate there is no throttle response for several seconds. When the engine does respond, the truck accelerates as if I have the throttle floored. Again this has happened on dry pavement. Slick conditions would have caused a spin out. 3. vehicle surges between 20 and 45 mph. Engine RPM continually jumps 200-300 RPM causing constant surging. Besides being very annoying, it would be dangerous on icy roads.
