i have the same problem. i pulled the throttle open. i then made sure the kickdown was is in its natural position.i then adjusted the slotted bracket until the rear of it was against the throttle arm .i then re-attatched the spring. now i get shifts so early that im in third at 20 mph and it wont kick back down.i have to manually shift it down. i reset it back where it was and now at least it doesnt shift so early but it wont kick down out of third but it will from 2nd to 1st.what am i doing wrong? does anyone have pics they can post of the correct adjustment?
