98/24v 73,550miles- tran started kicking in and out of overdrive around 45mph. changed oil and filter for tran and had dealer reboot - no help - several days later it has stop doing what it had been doing. I didn't have any problem on a quick acc. only while driving at a normal acc. and around 45 it would attempt to go in and then out and finally in overdrive. Dealer has no idea what the causes is other than to start swapping out parts at my cost. Any body out there who has had the same problem or idea of cause, please let me know.
