Those codes indicate it didn't shift at all. You have codes for no 1-2, no 2-3, and no 3-4. I suspect there may be other codes that you were not able to read. Usually those codes don't show up by themselves.

thanks mark for the reply i was hoping you would. well it it is shifting some but once i hit 55 i know its not shifting and reverse is hit or miss whether it works or not i gues i also forgot to mention it was seeming to run hot yesterday with no load on it im in illinois temps here have been around 100 and yesterday trans was 210 on and off i have done the 6.0 cooler upgrade last year after having troubles with high temps pulling camper. What can i do from here to help figure out problem is there a way to pull additional codes.

The way to pull additional codes is to use a scan tool that is compatible with this truck.

With those codes I can give you direction of where to look.

I have no idea if an AE can pull those codes or not. I've never used one.

The only one I've used is a Ford NGS.
