Agreed, Silver. I've driven '09 & '10 Malibus with A4 & A6 trannies, and the A4cars seemed to ease into the shift changes better than the A6. The A6 seems to shift down in the lower gears a bit harder than I like, definitely more noticeable than my A5 in my '98 F150 did. I KNOW Chevy can do better than that.
Much of the shifting quality stems from the programming Chevy has applied for the transmissions. Maybe some can come up with a better tweak.... ?
I don't notice any power draw on my I4 w/A6 with the AC on, but seeing that I use it 10 months a year in Florida... I dunno. Been a while since I ran without AC!
