Hey, I will be getting an th400 for the blazer in august, and put it in sometime before school. So I have a question, it already has an auto in there, but what difference in unbolting and bolting up is there from a manual? I unbolted and bolted up a sm465/208 5 seperate times 2 winters ago so I know how to do that, so is there any different proceedure? What about the colum shifter link and whatnot. Sorry I am not wise about autos so go easy on me!
