Re: Convert Allison 1000 5sp 2wd into 4wd

I used an Allison 2wd and connected it to a divorced np205. I had to have an intermediate drive shaft made up. I'm not sure it's any cheaper to do it that way...

I can't remember the computer stuff. I never drove the setup and dont know what issues with the computer/speedo came about.
