Just got my proshifted TKO II today! Questions

Basically, the synchros are removed and replaced with solid units that have maybe a third of the teeth to them. This makes it very easy for them to 'catch' when shifting gears; you don't have to wait as long for the system to slow down to the point they'll mesh after you've depressed the clutch. It makes powershift VERY easy and makes it very difficult to miss shifts. There's a sacrifice though. The streetability is gone. What makes it very easy to upshift makes it nearly impossible to downshift. You'll almost have to come to a stop to actually downshift; or depress the clutch and wait a long time (we're talking seconds here) before downshifting to any of the other gears. It also makes the transmission very clunky at low speeds. You'll swear that you're breaking something in the trans when you shift at low speeds, like cruising through pits. It scared the be-jeebers out of me the first time I drove one. You'll notice that with the proshifted unit, its real tough to pull the shifter out of gear without depressing the clutch. However, a light tap of the clutch and the shifter will almost fall out of gear itself and you'll be able to make the 2-3 shift with nothing more than one finger on the shifter.

Proshifting is worth at least two tenths on a low twelve second to low eleven second car. Nearly all of the manual T/S cars showed up proshifted this season...a true sign that it has become an all-out race class.
