Question after reading the tow/haul thread elsewhere in this forum. During normal driving with no cruise engaged and tow/haul not engaged, should the 8HP70 be downshifting on its own any time I hit a downhill and let off the gas? My Dak with 4.7 and auto never did this, and it was a plus for mileage.
I'm going in next week for an oil change, last time (first change) they did several unrequested flashes with the change. I don't seem to be making the kind of mileage I did initially, and am going to specify NO flashes without prior discussion & consent.
Anyway, wondering if the downshifts at road speeds 35-55 are normal.
Thanks,
DG
