It was an improvement campaign,not a recall,that is no longer utilized. I'm not positive but I think it sprays more oil on the clutch discs to keep them cool and eliminate chattering when taking off. @HondaTech knows a lot more about them than I do.
The clutch update parts are still available, but Honda will no longer pay for it.
There is a way to I.D the update from the outside, there's a thread on here somewhere with the pictures.
