On the highway today I noticed that the transmission would downshify going up hill but would not bo back to 6th gear after the hill was over everytime. Several times it stayed in 5th gear until I toggled the cruise down one MPH and then it would shift and I could raise it back up 1MPH and it would stay in 6th, This only occurred when ther was not a significant downhill when reaching the top. If you crested the hill and drove on level ground it would hang in 5th. Mine was built only two weeks ago so it should have the new trans calibration in it. Anyone else notice this?
