[QUOTE="GCATX, post: 1447763, member: 29405"] It has done it without the pedal commander. One thing I noticed, dunno if related, but while driving I generally accelerate steadily up to about 55 mph or so, then let off the pedal to an extent. Where I live, getting on the highway, about 1/4 mile from the house, 55 is the speed limit. 55 seems to be when it wants to shift into 8th, given my driving style. Am I somehow tripping up the computer's adaptive learning? Like it gets ready for a low/no throttle upshift to 8th, but gets confused that I am still wanting to accelerate? Doubtful, but I know nothing about the strategy. I do know our diesel motorhome will kick like a mule during shifting, if the tranny computer is reset (batteries disco'd). Shifting gets better with some miles. Seems opposite. Apples and oranges comparison though. [/QUOTE]
