After doing some research, $3,000 isn't that bad for a new transmission. Labor-wise, I'd charge you $750 labor if you have the V6. Maybe a little bit less for the four cylinder. It looks like good used transmissions are far and few between. And they cost a fortune. There's nothing out there for under a grand. Some of the salvage yards want over $2,000! Factor in the markup for parts, the shipping charges, Honda ATF, etc., it'd be hard to save you any significant money at all, let alone match that deal.
