You may think I am nuts, but
I would rather have a well tuned 6 speed to any 8 speed in my 2015 6.2...
Is it possible to change.
What's involved .

It would really cool if just a tranny and tcm change would work.

I know there were some early 2014 6.2 6 speeds built

Man, I couldn't see why you would want to do this. I love my 8 speed over the 6 speed. Either way good luck with the swap.

I'm out of the loop, GM is using 8 speeds now?! Wow... Is is a GM designed trans?

Ooops, sorry for the hijack.
