I have a 1999 civic sir (si USA), when I am Racing and I shift hard I get gear grind. it is a TSB but is Expensive to fix if the dealer does it. I was wondering if anybody has any info on it that might help me or that I would be Interested in?

 

what do you mean shift hard? like shift faster than normal or powershift with the gas down when you hit the clutch?

 

I never shift with the gas down. just when I'm racing and i shif, I pull extra hard on the stick it grinds a little goin into the next gear up.

 

every gear, or mostly just third? bad synchros. very common on b-series transmissions.

 

actualy its mostly 2nd but 3rd as well
