727 Kickdown Linkage Adjustment - HELP!

George I used the wide open throttle method and gave it just a little more, so I don't have full throttle, just a little less but that is where it works for me. Mine with 2.76 gears shifts out of first just under 50 mph if you run it up that far. Normally it will shift around 30 depending how I am driving and the shifts are good and firm. Hope this helps.
