Welcome to the club when it comes to shifting problems. The trannys on CD8 have had the engineers grinding their teeth since day one.

In my humble ( newbe parent/research-engineer, vis-a-vis FIRST-mentor/real-engineer ) opinion, you won't get that transmission to shift reliably without some major enhancements such as the forked slider collar that PMGRACER mentioned. Even with that, I don't know if I'd trust it to shift me to victory in the finals at the NATs. With a 3.5:1 ratio change, the odds are of it aligning are slim. Seems to me that, rather than using brute force, some sort of synchronization is needed. But simply filing lead-ins into the plastic ring gear will not work, at least not for long - as they will surely blunt.

FWIW from a freshman's parent, take a look here < http://www.dewalt.com/us/articles/ar...ordless&ID=695 > Maybe the ALL METAL gear set would hook up, or maybe (if it's kosher) a DeWalt/Bosch switch would do the trick. (How about that 3 speed tranny??) Simple and FREE pre-test would be to visit local tool store and check the DeWalt shifter?

I have some "pie-in-the-sky" ideas on how to synchronize. But it would involve considerable bandwidth and a whole bunch of hand waving; contact me directly if you're interested.
