I have a Holley 750 on my 84 305. It always has jumped like crazy between 1st and 2nd. I was told that I need a overdrive transmission braket made by Holley. So I went and bought one. Now how do I put it on (I see where it goes, but im not sure what is to happen with the old transmission braket that is in there already). And seconly how do I get the kickdown cable on properly (I was told it was a 2 man job).. Any help would be much appreciated...

 

The problem isn't usually the bracket. Where the cable connects to the throttle linkage is different on the holley and has a shorter thow. When you set the TV cable to be maxed out at full throttle(like it should be), the TV cable becomes pulled too far at light or no throttle. The tranny thinks you have your foot in the throttle when you actually don't. I think you can get a arm to correct the problem. I just live with mine.
