Re: Grinding the trannies : P
i rebuild trannies and i did so professionaly for a couple years. i have rebuilt some honda trannies before , here is my guess on whats wrong. you have a busted fork and it is not the syncro at all, your syncros should still have a perfect point to them. when the weaker leg of the fork breaks from hard shifting it binds your sliding clutch and engages unevenly. if you were to push the shifter softly into 3rd gear it shouldnt grind. assuming you are going to replace the synchros would probally be a bad guess, just try shifting softly into 3 rd and you will know. i had a crx si tranny that had 2 busted forks 1st/2nd 3rd/4th it would grind going into third and downshifting to second, all i did was replace the forks with ones from a dx tranny and it was the smoothest shifting tranny i ever had.

what do you mean busted forks? I know those forks arent that easy to break, plus the are in place by the housing, and only moves up and down while shifting. I am no expert but I think he is correct about his synchros being worn.

Re: Grinding the trannies : P
i'm having the same problem with my 90 si grinding in third gear. i've got the housing off cause i just pulled my engine out and felt like it. anyways, where should i look at the forks to see them broken off or whatever. everything in there looks fine to me, but i'm no tranny expert
