Switching out Transfer case

[xanatost]

I got a 98 auto transfer case with them auto 4 wheel drive switch and I am wanting to put in a transfer case from the 96 I got. It is the floor leaver one. my questions is:
1) is it a bolt up to my 4l60e, if so
2) do I have to do anything with the ecm? if it does
3) can I get Black-bear to remove for the ecm?

not likely to bolt up. iirc the 241/243 has a 4 bolt adapter to tranny. 246 have a six. does not mean you can change the tail housing of tranny. and the ecm and abs module need to stay involved with the 4wd system. how they interface with the older unit i will have to look into if you want me to.
