I recently had my Avy at the dealer for the Heated washer fluid campaign. While waiting for the tech to just pull a fuse, I test drove an 09 Avalanche with a 5.3 and the 6L80E with the tap "up" and "down" buttons on the shifter. All I can say is I like it allot!! The trans shifts very smooth and the acceleration is very impressive and when you get on it....The truck takes off not all that noise from the engine and no acceleration for 4 seconds which is well documented with the 6.0 and 4:10 gears for those of us with that setup. Off the line the 5.3 and w/6l80e would easily jump out to a 2 1/2 truck lead on my 6.0 Avy with the 4:10s. I would think the the 6.0 setup would have been even quicker even with 3:08 or 3:42 gearing.
Okay... Enough, All I want to do is put that trans in my Avy. There's a tread on the Trailblazer SS boy's web about this very swap and there's all types of issues with putting that trans in that platform. Since this setup is now available on the 09 then there shouldn't be to much needed to make this work in our 07 and 08 Avy's . I want to do this to my Avy, because I can't justify trading in my "07" for a "09" just to get cooled seats and the 6L80E.
