6L80E Behind Duramax?

[hdd-max]

Mike or anyone else,

I just got a 2008 Denali XL AWD with the 6.2 and I assume it has the 6L80E in it? I have a spare duramax laying around and was scratching my head thinking I should put it in the Denali. Would the trans and AWD thats in it work? How much power could it be made to hold if built? Right now it is just a thought that I am exploring.

Maybe I should just leave well enough alone.... Them things are NICE, and have pretty dang good power.

Alot of the guys on the g8 board are running 500+hp on the 6l80 without any issue but a G8 only weighs 4 k and they don't make the torque a duramax does

I don't think it will hold up a 6L90 might work on a stock Duramax motor

I am not even sure thats the trans thats in it? I have been looking but cannot find the info.

I am pretty sure it is the 6l80 the 90 only comes in HD's Vans and the CTS-V

I would just "PRO CHARGE " it and save some head ache and money , I raced an H2 with a intercooled pro charger and that thing hung with my truck decent , it didnt run with me but it was pretty impressive for the weight of the rig .

yes the denali has a 6L80.

The 6L90 is a pretty solid trans, and is rated by GM to hold 520ft lbs.

I dont know what generation dmax you have sitting there but if its not an LMM it wont work. LMM electronics are the only ones that will work in a new body style denali.
