If the problem is due to a computer or sensor the O/D light should flash or check engine light should come on. Check the fluid to see if it appears burnt or smells burnt. If the fluid is overfilled then that could also be a problem.

Did you have the transmission serviced recently? How often do you have it serviced?

I don't have any recommendations as far as a shop your way. The dealer probably would be the best because they will be aware of any updates for the transmissions. They only see Dodge so they will be more familiar with any common problems.
