What kind of numbers are you putting down to the ground now? I'm not so sure it would be "cubes + STS" as much as just sheer power.

My worry is running into what quite a few others have. Blowing a built 65, over and over again. What would the cost on that be? Even if it's covered, $700 to remove and another $700 to reinstall could add up. You're right, I'd hate to drop $4000 completed for an 80 though...

Look here: http://www.silveradoss.com/forums/index.ph...wtopic=9194&hl= <{POST_SNAPBACK}> Ahhhh yes.... read that one. That doesn't answer the question as to whether the setup is different on the Denali when compared to the SS. Does anyone know?

I'm at the point where I need a new Trans. The 4L65 just isn't holding up to an extra 200awhp and 225awtq at the wheels. The trans is slipping BAD going from the 1-2 shift. Starts to shift at about 40mph and doesn't actually get into 2nd until about 60mph or so. It seems even the built 4L65's aren't standing a chance with a lot of power. I also read out here that no one has done the 4L80 swap in their SS? Since I have a Yukon Denali with AWD, is the setup the same? I know the SS has a longer wheelbase, thus some different parts. Does anyone know the possibilities of putting in a 4L80 into a Yukon Denali? Or is this uncharted territory?
