Hondas and Acura use a different automatic transmission design and from what I've heard are more costly to repair (labor). My parents had the automatic that was in my car rebuilt by a reputable local shop and with parts and labor it was around $3,000. Yes, three thousand dollars. The fresh rebuild will of course give you a longer lasting and better performing trans but for that cost you could buy another car. E-bay or forums have them going for around $200-$350.
