I love tiptronic on the Mazda 3, I ride it really hard, anything below 40 km/h when I am doing spirited driving, I will shift to 1st and floor the gas pedal just a split second before the shift, I just get pulled back in my seat no jerking. Downshoft as low as you can just floor the gas at the exact moment of the shift, you will feel the speed with no jerking.Da 6 said:*meaning if yu are at 4th at 45mph floring it will only get you to 3rd....drop to 2nd for a split second or 2 and you should be fine. if you do this on a regular basis invest in a tranny cooler.
