There shouldn't be any reason to replace the tranny.

If you need to replace the clutch & assembly (pressure plate, throwout bearing) then expect ~$300-400/parts for something worthy like clutchmasters stage 3 setup (highly recommend it for street or HPDE use).

I also recommend jumping up to using the flywheel (plus pilot bearing) from clutchmasters ~$250-350/parts.

The swap is a pita until you've done a couple & then you realize it's not that hard to do on your own & save the labor (Acura will charge ~$500 for labor alone.

If you have to replace/rebuild the tranny(gearing/case) I hope you have deeeeep pockets - labor will kill you unless you can do it yourself or have someone you can just take the case to after YOU have pulled the tranny yourself.
