My truck decided today that it didn't want to go Vroom anymore. I got a rail pressure high code and a transmission OD circuit voltage low (P0973 code). I think the tranny code made the rail pressure code set. Truck is stuck in 3rd. Spoke with Dave, he's sending a set of selenoids to test, if the new selenoid is plugged into the tranny harness and doesn't set any codes just hangin there with the key on, then I'll go in and replace them in the VB.

Anyone else experience this before? The only way I can drive the truck is put it in neutral for a few seconds, then quickly put in 1st. from there I can manually shift up to 3rd.
