06 Dodge 5.9L Transmission Help

[Xhurley]

Hi this is my first time asking a question on the forums I find you all are very helpful and great hope you all can help me!
I have a 06 Mega Cab 5.9L
w/ Bully Dog GT Tuner.
So here is what happen I took off this morning and my truck would rev to 2800-3000 RPM before it would shift. After that I had no problems when I noticed this I checked my tuner and all my temps were fine but my transmission temp was reading 35 degrees and wouldn't raise at all. I have no error codes or anything. I was wondering what I can do to fix this. I have unplugged batteries to reset but nothing this was something I was told to try.
Thank you guys sorry if I dragged on.

Suggestion

This was suggested by another guy!
"Take the tuner off then pull all 4 battery post terminals off wait 10 min then touch both batteries cables together. Yes together on both sides and that totally drains the system. Used it on my 06 when my six gun messed up with my auto shift patterns. The guy at banks told me to do that over the phone so i did and it Never done it again Off coarse check u fluid, give ur tranny a visual look over"
Anyone have any other ideas? Thank u

Is the truck throwing any engine codes? If so, what are they? Also, did you check your tranny fluid to make sure you are OK there?

There weren't any error codes and I checked the fluid as well and it was perfect! I was told to check the "governor solenoid" does anyone know much about this part going out?
