When driving the odometer starts bouncing and the stabilatrack and traction control come on. As I slow down it hard shifts down, 1st gear being the hardest. When I go to accelerate the transmission stays in 1st gear. I have to pull over, turn the truck off and back on. If the manual setting lights up when I shift to it I'm good, if not then I repeat. I have already dumped a bunch of money on this truck for sensors and what not, trying to get a good feel for what's wrong before I pay the dealer to find out and then pay them to fix what they think it is.
