Guys and Gals. I bought a 2012 Silverado last year, crew cab 5.3 with the 6 speed auto. I am quite disappointed with it. This thing lugs when accelerating from a slow speed, hunts for gears in traffic, etc. I put it in manual mode just so it'll shift right when driving in town. To get it into passing gear on the highway I have to dick around with the gas pedal or stomp on it to shift up. No codes coming up when I take it for oil change, and the dealership says "hay we can't find anything wrong". My 1996 tahoe (only 75k miles on it) shifts so much tighter and better than this 2012. Only thing I've done to the truck is put a Volant cold air intake kit on it. It has increased overall power but anemic tranny remains. Any advice?
