In a change from previous reports about the timeline for six-speed transmissions to start showing up in GM’s half-tons, other than GMC’s Sierra Denali, Mr. White says, “We’ll probably roll out the six-speed earlier than 2009. You’ll see them in one model and then another.”
And as six-speed gearboxes deploy, the 367-horsepower / 375 lb-ft 6.0-liter Vortec Max V8 will be retired and replaced with the 403-hp / 417 lb-ft 6.2-liter Vortec V8 across the entire light duty lineup. Today it’s only found in the Sierra Denali (http://www.pickuptruck.com/html/2007/gmc/sierra/roadtest/page1.html). The 6.2 is the most powerful naturally aspirated V8 currently available in the half-ton segment.
I'm not sure if by light duty if they mean only half-tons or the entire light duty segment of trucks which would include the 2500HD.
