Fortunately, we were ready to face what could have been a problem with the transmission’s throttle valve (TV) linkage. We knew that our late-s overdrive trans would require a different kick-down bracket when going to the Edelbrock carb. This bracket is held by the left rear carb stud and guides the throttle linkage and the TV cable. Having the wrong bracket, adjustment, or not hooking this up could mess up your transmission’s performance. We found this bracket at a performance trans shop and GM offers them new under PN 22504927.
