Is it possible to do this swap? I'm looking to get a little better milage. Not apposed to a 6 sad manual but if I can keep an auto and get an extra heat that would be nice.

 

Anything is possible, You'll need to modify or fab mounts. You might need to change the length of the driveshaft. That's all the easy part.

Now you'll need to create a wiring harness, and then write a computer program to make the trans shift behind a 6.0L.

 

The 2005 automatics and the 2008 automatics are the same transmission, a 5R110W Torqshift.

 

I assumed he meant the 2011 six speed auto. You are correct, the 2008 is the same transmission as the 2005.
