Hi! I have a 95 blazer that is OBD1 with an auto transmission and the np231 manual transfer case. I also have a 95 ZR2 truck that is OBD2 with an auto transmission and the np233 auto transfer case, and a 97 ZR2 truck OBD2 that is manual transmission with the np233 auto transfer case. I am parting out the blazer and I would like to put the np231 into one of my trucks, preferably the 97 if compatible or the 95 as a last choice. Has anyone here done either of these swaps? What issues might I run into doing this? Thanks in advance!
