Well if you have never had the trans serviced then now would be a good start. Since the shift goes bad once its at normal operating temp then you may want to have the trans temp checked to see if its within the proper spec. If the trans temp is in the proper operating range then you have other internal problems. You will need a proper diagnostic performed on the trans. Does the trans go into fail safe mode? How many miles on the vehicle?
