Can anyone tell me if this swap is do-able? Do you know how to go about it?

 

Sure it is. You basically rip all of the guts out of the transmission and swap the 4wd tail shaft in.

 

if you really wany a 4wd i think itll be alot easier/cheaper just to go out and buy something thats already 4wd.

 

I would buy a 4WD model instead.

 

Correct-o-mundo!!

 

Let me clear this up. I have a 4wd Blazer, it has a 4l60e that doesn't shift properly. I'm having trouble finding a used tranny that is already set up for 4wd but there are seveal trannys available from 2wd models. Can I alter the 2wd transmission to use in the 4wd application. I appreciate the responses, it is my fault that the question was not clearly stated. Swartek thank you.
