You're really not supposed to adjust shift points with the kickdown cable. If your shift points are too low, then the cable isn't moving exactly when the throttle moves....Lokar makes a nice piece, and there are a few other companies who also make some cheaper ones. I made my own after studying how everyone else makes them. I used a heater push pull cable and some home made brackets. adjustment was pretty easy, I can also tighten it up to change the shift point.
