I have to say I believed this was possible 2(almost 3) years ago when we heard about Luis's car... wish we still had the HA.net posts, I remember some mention of european car mag's discussion regarding this. Wonder what it would cost to rent tms for the day and do laps at say ... 125 all day. It would seem pretty easy to be making a whole bunch of left turns at 100 plus if not dead on 125.

Your VIN number sequence is specific to the North American market. If you want to investigate changes to the gearbox design, especially with respect to the European market, you may be better going by the gearbox serial number. If your gearbox uses the same number range as ours, then you should be able to tell if your new one is newer than Luis's replacement. I don't know if my replacement gearbox had the high speed fix. I'll try to find the number for it.
I can get the other number off the tranny . . .

It will take some time for all this to sort itself out. Until that happens, I was wondering if adding extra fluid to the transmission case might help compensate. Or does that have undesirable side effects?

cmnsnse,
So the oil level on your trans was OK when the failure occurred? The gears on the main shaft actually heated up enough from the needle bearing failure to burn the oil level onto the gears?
You've convinced me that there may indeed be a high RPM oiling problem under sustained high-speed driving with the tranny that causes the pressure and volume to drop enough that the bearings could be compromised. This IS strange though, in that nearly all manuals use no pressure lubrication and live just fine, BUT if the Honda engineers did not design the bearings in this tranny to be splash lubed, and indeed they REQUIRE the 4-5 PSI you've measured to live, then you are really onto something here.
I seen muffled references to failures in Europe, and to a modification from Honda to the trans, but no posts to back this up. Can we get any proof of this to help your cause with Honda? I really think Honda should help you out here, BTW, no matter what the cause of the failure was.
Keep at it!

While I find the information and research interesting reading, I personally would not change anything based upon the experience, testimonials, and recommendations of a small handful of owners.
I'm not so nieve (sp?) to think that Honda can not make an error; however, I'm in no big hurry to dismiss their engineering and design either. It never ceases to amaze me how quickly some folks want to believe that a shade tree mechanic can out engineer a respected engineering department. Perhaps it's built into the American culture that this how it works -- and there is evidence that at times it does work that way. But, the odds are the manufacturer's have thought it through way more than folks want to give them credit for and they have built in many more variables than the average person would ever consider. No offense cmnsnce, but for now I'll not change a thing and I'm not the least worried.
