I have a 2001 4.7 auto (45rfe) with electronic transfer case (233) and I'm looking to swap it for a 242 with 2wd, 4hi, 4ft, and 4lo. I want to have the awd setting for on road use in rain, light snow, etc. When using 4lock in snow that goes back to pavement it binds up my case. They only plow main roads where I live, back roads will be full of snow. It's a pain to switch back and forth all the time. But I still want 2wd for towing, burnouts and general day to day driving. I know they made a version with a wider chain for V8s, what could I source that out of and what if anything do I need to change for it to fit in my truck?
