Default AWD astro to 4x4

Hi All

I'm new to this forum and I did have a 1998 S10 Blazer that I loved but I needed to up size for family reason's and I now have a 2001 lifted AWD astro, I'm looking to convert to push button 4WD like I had in my 98 Blazer, I was wondering if anyone here could help me out in the way of information and part number's I would assume this would be the same procedure as converting a Typhon, Cyclone or a AWD Blazer to 4x4. What would be the best T-case to use NP233c or NP236c? (is there a difference)also I would like tohave it be a one button push no separate button pushing to lock up the front differential just like my old Blazer setup, I will also assume I will need a different TCCM for the new setup.AWD is nice but has limitation's like I'm currently only getting 10 to 12 MPG's with 31x10.5 tire's I think that2 wheel 4 wheelmode would bring that down I also liveand travel the North East and I think true FWD is a better option thanAWD in the snow and it would be nice to be ableto hit the sand on the beach if I had some time, any help would be appreciated for a GM brother.

Well if it is like the 98 and newer bravada then it uses theNP-136 which is 2wd until it detect wheel slipping. This was added starting in 98 to help with gas mileage. It is by default rear wheel drive so it is really a4wd rather than awd like it is called.

^ yes, the 01 Astro has the same transfer case as the 01 Bravada, staying in 2wd until slip is detected.
