who's been having to add transmission fluid?

Enough of a problem that they found a fix and replacement parts. They don't RD replacement anything unless they have a issue.

Seriously though, I can't find more than one thread of people complaining about that problem from 2014-2016.

Hell I always put a quart in each and rode. Never thought to really check until Webb posted on this forum . Look at the **** he stirred up.lol . Mine isn't bad but it's happening and I'm more worried about my clutch.

The quick answer to this, and I'm only repeating what my SM told me the other day, is yes....... it's been tried already....... by MoCo none the less. As far as the results, we don't know.....YET.... (see below). But venting the primary is NOT the fix. It's only troubleshooting data to help determine if the tranny fluid is being sucked into the primary, or pushed into the primary, that's all. If you break the vacuum with a vent and it still transfers, it's being pushed into it. Then they'll know whether to concentrate on the input side or the output side of the primary. I'm leaning towards the pushed theory......

I think you could be right about it being pushed or “pumped”. Basically the helical cut gears are picking up oil and when the mainshaft and counter shaft come together they push it in the direction the gears are slanted. It wouldn’t be to big a deal unless the cases have been machined so close that they actually make the transmission into a pump, pushing the oil through the bearing, filling the cavity and pumping oil through the mainshaft. Oil is blocked from going through the countershaft bearing by first gear. So depending on how your transmission case was machined it determines how efficient a pump you have. This is why some bikes transfer and some don’t. It is also why some transfer a lot and some just a little. In the TwinCams that did it vacuum might have been the cause, but I don’t believe that’s true with the M8’s.
Seems a thin shield over the mainshaft would wall off the flow path.

So since this TA has come out, and I notice there is a "fix" listed in the doc for pre-M8 TC models, I'm trying to understand how different the components would be and why its seemingly so hard for them to find a fix for the M8's.
If two different models are having the same exact issue, there has to be a commonality somewhere, right?

I have given a couple of updates here but not for a while. Against my better judgement, last Saturday I went for a couple hour ride and kept the RPM's at around 4K as much as I could. I had alway thought maybe I didn't see the issue because of my riding pattern. This included a stretch of time over 5 minutes as well. Several hours after I put it away I checked the fluid and all good. I guess I am one of the lucky ones as well perhaps.
