    When driving at 65 it feels like the transmission keeps coming out of overdrive. There is no slipping just switching back and forth

    The transmission in over drive goes into lockup mode on the highway while cruising (great for better fuel mileage). If it needs a little more power the torque converter will unlock. This feels like a down shift into a lower gear, but it isnt. I'm not sure if it is the same issue, but Dodge trucks had a problem with the computer programming of their trannys in the late 90s and early 2000s. On flat ground at around 65mph the torque converter would lock and unlock over and over. This would start around 1000000 miles. You either had to speed up or go slower for it to stop. 65mph was a nogo. To fix this you either bought an aftermarket programmer that also changed the shift points ie for towing or more power, or you took it to the dealership and had them flash the computer.
