Question. What is the difference from like a 94 full size 4x4 auto blazer transfer case floor shift and one from like a 01-02 that is a auto floor shift? Curious if I can use mine with my 6.0 and new transmission. From a 01.Looking at running a 02 6.0, 02 4l60E 4x4 trans and my 94 full size blazer transfer case. Worried about the speedo for the computer.
