I hope it's a an easy fix for you and not a fork in the road moment. You have a very well maintained RL and should not have to deal with this outside warranty.
The part number was a Honda reman part number.Because yours isn't a warranty job they don't have to get the reman from Honda's source. They are free to get from any number of remanufacturers. A brief look at several leads me to Jasper which has a 100,000mi and 3 year warranty on their remans. They have been known around here to be the Premium supplier for Engine remans in the past. But their warranty states the obvious. They stand behind the reman job. You should ask where they are getting it from. And ask for the address they return it to. That'll tell you a lot of where it came from and who is rebuilding yours.
I was thinking more like those on the forum who got a replacement trans followed by failure and mentioned it here. I don't think there have been any. Silkie will be a good statistic.Warranty replacements and even out of warrant replacements (unless you pay the core charge) will never be opened by customers or dealers.
