Editing Help with my 93 chevy trans. 4L60E

Hi i have a 93 chevy Silverado four wheel drive and it has a 75 build 350 crate motor and also its carburated with an edelbrock 650 carb.and intake, No electronics! How do i get the stock trany to shift into third and overdrive. I can column shift into 1st and 2nd but no third and fourth. Its a fully electronic tranny. What other trannys would you throw in to fix this if the stock one dont work? '''This is a WIKI page''' .. it is not a discussion board. The 4l60E needs a controller to operate the shifts and pressure control. Check out : http://www.hgmelectronics.com/ home of Comp U Shift controllers
