Question for those with transmission oil transfer issues

[Capt.Bob]

The dealer did the service Jack.

That's the problem, I didn't check either primary or transmission fluid levels after the 1K service so don't know where they were. I'll probly do the 5K myself over the winter as I believe all they do is an oil change - I'll do 3 holes + filter and will have a much better handle on it for next year.

Danny, I don't know if it makes a difference but I use Harley Syn 3 for the crankcase and Harley Formula Plus for the transmission and primary holes. I know there are a lot of other good lubrication products out there but with the oil migration issues etc., I have decided to stick exactly with Harley's formulations. I don't particularly care to use the Syn 3 in all three holes because I am not comfortable with putting a partial synthetic (Syn 3) in the tranny or primary areas. The Formula Plus is reportedly designed specifically for transmission/primary applications. I was getting some oil usage up to about 5600 miles on my 2017 M8 TGU but now virtually none for the past 2k miles which is more like my 2016 103ci TGU that burned very little oil. The tranny fluid has not budged a fraction of an ounce since I did my own 5k service. I check it regularly and have not noticed any changes in level for approximately 2900 miles. Do remember when checking the tranny dip stick to only tighten the threaded stick down to where the rubber o-ring contacts the case and then bring it back up to get a reading when the engine is cold.

That does make a difference Bob, I was just mulling over this very same subject....thanks.

Fearless, could you please post specifics on what transmission dip stick you bought & where you bought it?

Thanks.

UPDATE: I just realized you don't have an M8 & I don't know if the T/C dipstick is the same, but I would appreciate the info.

Thanks Fearless for posting your order info, but it won't work for M8's. It's for T/C's only. Mine is a 2017.

I have an idea for making my own. It could very well be a low priority winter project.

I'm thinking of cutting about an inch off an old hex wrench and epoxying it to the OEM dipstick with some kind of cap on it. I play with it later.
