So let me set the stage....
Bone stock 6.0 (new to me) hooked to our new to me 5er roughly 10K lbs. Pulling a pretty stout hill running 65ish, truck down shifted to 4th and held that gear for roughly 1 min, fan kicked on, truck was working a bit.
As we neared the top of the hill I lifted just a bit and the truck decided to shift back into 5th when it did it instantly threw the wrench light. I pulled over at a rest stop for just one second. Key cycle and wrench is gone. About 15 mins later same thing, threw the wrench again... Instantly as it shifted from 4 to 5 at pretty decent throttle/boost.
So, got home... forget to pull the code before I shut it off and the code is gone.
Anyone have any ideas whats up? It never did this in the 4K I've owned it so far.
