451 is for the manual, 451A is for the auto (or manual)...at least that is my understanding. I didn't have that problem but I do have the manual so it must have something to do with the kick-down switch and the sprint booster. Just out of curiosity, did you do the throttle body adjustment after installing (just a thought at something else you may want to try before uninstalling)?
