mudhen, just a clarification. I drive a 2011 GMC Sierra 1500 with the 403hp 6.2L and the MAX trailering package. It has a 6L80E transmission (six-speed). This motor is not available in the 2500 series. Those use the 360hp 6.0L, with I believe, a 6L90E transmission. FWIW, I love this '11 pickup. A big step up in power over my previous '08 5.3L, with a barely noticeable decrease in fuel economy. Well worth it, IMHO.
