The TKO's advantage is a lower 1st gear, and less RPM drop on the 2-3 and 3-4.




Well, the numbers don't lie, but your ability to shift it quickly is also a factor in maintaining RPMs and in that case the Passon is the hands down winner.




There's only so much that can be done to a transmissions hard parts to make it shift smoothly or fast. But when a trans shifts, the countershaft, pilot shaft, and clutch disc must all be slowed down until the shift ring and syncro speeds are even and the next gear can be engaged. Lighter parts help, but this FACT is an inherent flaw in transmissions that have wide ratios and large RPM drops between gears - it simply takes longer to slow the disc down to 3600 than it does to 4400. This is why a trans may shift smooth as butter at 4500 and horrible at 6500. Wide ratio's are also harder on the wear parts - again, because they have to work harder to slow down the front of the trans.
