OK - I specialize in "Any Ideas"

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.
