I leave mine disconnected and when i get a chance to drop the pan and change the filter im going to unhook it and plug the hole. As far as erratic shifting goes, thats all in the modulator, mines still the original one and works great, just have to make sure the vacuum line is good and not leaking, if that modulator doesnt get any vacuum it will only shift in WOT so at like 4000 rpm. But if you want to use the detent cable, the way to "adjust" is the same way you would with a TV cable on a 700r4 or 2004r. Pull the cable all the way out, then open the throttle all the way, technically they should both be even when at WOT. When i had mine connected it was loose like maybe a 1/4 to 1/2" of movement when the metal end was on the bracket when it was in idle, but at WOT it was just perfect. I ran a holley carb with a 1 inch spacer but i used the bracket which relocates the throttle cable and kick down cable.
