Swap out Allison 5spd to 6 spd manual?
My brother has an 04 LLY w/ the Allison auto. He is wanting a 6spd manual transmission. How difficult would it be to change it out and what all is needed to be changed, if at all possible to do? Have any of you guys done this before? I personally think he should keep what he has, but he wants to do the shifting.
