Your '01 and my '05 only has the overdrive selector on the column. The coach will still work up quite a speed rolling downhill if you don't watch it even with the OD selector off. I agree, shift down at a slower speed if the hill is steep.
Another anomaly is that the cruise will kick out when under a heavy pull uphill.
I don't think our tranny's have auto downshift when tapping the brakes either. If someone knows better, I would like to hear about it.
Life is a journey, not a destination.
