I would change the transmission fluid and add lucas oil additive and if it still doing the same it could be an internal problem
Ill try that next but could it possibly be a sensor or the tranny getting hot maybe because both times have been after about 40 mins of driving it
It could be but i cant think of any sensor that would do that
Okay just trying to think of other possibilities and also a friend of mine said that your not supposed to change the tranny fluid after 100k but im not sure avout that
Check the fluid if its nice and clean it should still be good but if its dark then it needs to be changed
