after a few runns with DS this is what I'm getting . 2-3 shift, 57 mph/5000 rpm / 3-4 shift, 94 mph/5100 rpm . does the 3-4 seems a little high ? am I in the ball park with both the 2-3 and 3-4 ? car in highway cruise will not shift from 3-4 at around 75-80 km/h unless I lightly take my foot off . converter is a non/LU 9" AC . any suggestions ?going to consider loosening up TV cable . many thanks .
