I have spoken with several people on both the tko and t56 6 speed and have some first hand experience. Both trannies seem to last pretty well on the strett or drag strip under hard forward acceleration. The problems start on the road course when you ask these tranny's to down shift at speed. On a down shift, you are loading the back side of the gears. Just like an engine, if the tranny fly's apart, it is usually on deceleration. Also, both trannies sometimes snap off the 3 little detents in the syncro assembly which makes it tough to shift at all. Bottom line, both are good all around and will take the abuse and hp as long as they are not driven really hard on a road course in high hp applications. scott.
