07.5 no mods auto 4x4 when you shift it into reverse gives a hard thud and goes into reverse then when you put it in drive gives a hard thud and seems to be stuck in third gear. That's my guess does about 40-45 just about red lined. Won't manually shift won't shift when revved out. I've heard a solenoid may cause this any advice?? Will not shift up or down in drive no matter what position you put it in. There are codes but truck is three hours away till I can get a trailer there friday or saturday.

 

Came up with some transmission control codes and range performance. Cleared them drives fine.
