Sounds like your synchros are on their way out.. time to look for a new tranny or get a rebuild..

I have a ZC tranny I am about to put up for sale


Some things taht may help, Honda MTL, or Double Clutching..

do double clutching...
i can save ur synchros from being broken this way,....
what u have to do its match the RPMS with the shifting point.. means that u have to rev the engine a lil before u let clutch go when downshifting.. so the speeds inside tranny get equalized

yup, try doing this....when coming to a stop, about 20 mph, try putting it in 1st...it wont go in, its the same deal with what your doing now jus your going faster bc your in a higher gear, you either have to rev-match or slow down enough for the gear to pop in.

what you all just said doesnt seem like its his problem, if it only grinds when goin down a gear why the synchros, you wuold think they would grind going into 2nd from first then too if it was synchros???

thats why I explained what i did, hes not rev-matching but even so his synchros are "worn" not bad, thats why they wont grab when he shifts from any gear other than 1st bc its not rev-matched.

tranny rebuild kits are from $100- $200 bucks..

and I have a friend that will rebuild them for $100, if you bring him the tranny and the kit.

I just takes time.... like anything else on a Honda once you get in there its not that bad..
