anyone know what trans i can use in 96 4wd blazer
 

since I'm gonna have to replace my transmission in my 96 blazer 4wd with a 4.3 vortec , I need to know what year model of transmissions will bolt right in and work with my existing computer and transfer case? I don't want to have to make any modifications or buy extra parts in order for it to work correctly. thank you for any help in this problem

Are you going to replace it with another 4L60E or considering an upgrade to other transmission?
