I have a 2011 1/2 ton Chevy 4x4 with a 8 inch lift and 35 inch tires. I assume I have a 6l80E transmission. My question is what are these trannys rated at ? I just purchased a Magnusen supercharger to bolt on top of the 5.3 to make the power. Now I'm worried about tearing something up.

 

Idk a whole lot about them buy from what I've read they're pretty stout, you shouldn't have to worry.

 

you can take some of the strain off the trans by regearing the differentials too. its a good idea anyways when putting bigger tires on your truck

 

Sorry, should of listed that also. Regeared to Yukon 4.56's already.

 

you should have the trans re tuned. they are picky about rpm and speed variations when deciding to shift.

 

Who does this ?

 

In Texas you should have a bunch of shops. I'd start with sponsors on the right and then try a search on this forum.
