Hello,

I have a '75 Blazer with a 3 on the tree, and I'm looking to change it to an automatic. I have a bead on a cheap 700R4 out of a '91 GMC 2WD. What needs to be done to put this in my Blazer?

Can I basically remove the 2WD tailshaft, install a different output shaft, and bolt it to my transfer case?

Thanks in advance for any help or advice.

Brian
