got off the interstate and truck shifted down hard. I have read about the trucks doing this on here. but it wont shift any more. is the tranny bad? i had to roll home doing 26mph at right at 2k rpms. and im sure it wont shift i ran it up till it hit the limiter:mad: tried stopping manually shifting tried towhaul. tranny fluid was a little low and temps never got above 200 took forever to get home any help is appriciated.

Get a code. You can cycle the ig. switch a few times and it should start shifting normal.
