The link below will tell you everything you need to know about the Honda Class Action Lawsuit settlement, which applies to your car. In fact, the symptoms you describe fit the descriptions give by other Honda/Acura owners, and as described by Honda Motor Company.Once on the link, click the blue boxes on the left to learn more.Essentially, the settlement extended the warranty out to 109K miles, or 7 yrs, whichever is less. I understand that the problem was due to a design flaw in the 2nd & 3rd gear clutch packs...due either/both to defective quality of subcomponents, or due to inadequate oil delivery to those components. The solution has been to replace the transmission with a factory rebuilt model...it requires changing the unit.You might read/download the info provided below, and then contact your local Acura dealer to discuss just what (if anything) they might do for you. Also, if you were to bear the full burden for replacement, the cost would likely run somewhere in the $3K range.Hope this helps, and best of success...
