from the gearbox especially at around 4000rpm...my mechanic had to initially sand down the bushing at the bottom of the shortshifter in order for it go into reverse properly (w/o sanding left the spring all the way down meaning i can go into reverse without pushing down...a big no no) now i'm afraid that he might have sanded "too much" and has no left a gap between the bushing and it's surrounding..my question obviously is...what can i do to fix it? (can i put honda's oem grease into it to make it stop?) or (can i put like some sort of foam between the bushing and it's surrounding in order for it to stop?) or any other suggestions would be greatly appreciated at this time.

btw i checked to see if any screws were loose along the process and it isnt.

I think I'd get a new bushing, and a new mechanic, but even if you do both, your shifter may still buzz.
The main thread discussing the problem starts here.

 

Mine vibrates a little bit but nothing that you could hear. However, the shifter removes the sound deadening that comes with the OEM shifter so your probably just hearing the transmission...its quite audible
