Kickdown with transgo tf3

i bought a tf3 kit based on it being advertised as full manual. car is street strip and converter is 3800. instructions said nothing about having to use the tp linkage. shifts were firm with lever wired back and seemed to operate well.
have since stroked and gone turbo with a CRT reverse pattern vb which absolutely slams gears. preferred the way the tf3 shifted to be honest.
