The problem was the "valve body". The dodge tech immediately knew the problem from the discription. This is critical, if you run much from start in 3rd gear, it destroys the clutches (disks) in auto-trans resulting in a very big repair cost. I was lucky and took it in after two times it did it. Cost of part was $700 and labor was $280 (4 hours @ 70). Misc 4+ oil made the bill over $1,100. It has shifted fine since.
