I have a 2005 KS Pusher 330 Cummins and Allison. This push button thing total confuses me! Give me 9 speed manuel any time.
I can't seem to feel when I need to downshif on the climb or if it is auto shift. I'm short, so I have to look over and behind my left arm to see the mode. Do I have the economy? I down shift as I get steeper, and also use my jake down hill and stop and go. I think the worst pull have been on so far is HWY 160 from I-15 in Vegas to Pahrump NV. That was work! The worst road I wrongly got on was Hwy CA 178 from Lake Isabella, CA to Bakersfield, CA. Not for the weak of heart!
