Looks like your kickdown cable adjustment at the bracket is maxed out. I would give it a bit more slack. Be sure the kickdown lever on the trans returns fully to the front after full throttle. On mine I had to make a bracket and put a spring to the kickdown lever to make sure it returned properly. The springs that came with the Lokar kit did fine for returning the throttle lever to fully closed but the kickdown return needed some help.
