Sumping and transmission oil transfer to the primary are 2 different issues.
Good catch, either way they weren't willing to handle it. You are correct though, the sumping issue was separate from the transmission breather TSB. I heard of a lot of sumping issues when I bought that bike, so I was sure to get the extended warranty. Luckily, no issues arose from it.

2021 Ultra purchased July 2021, now with 44k miles, only issue was rear TPMS kept errantly going off for a flat tire / low PSI.

Going west in a couple of weeks... should add another 4000 miles,

I love mine. 2020 Ultra Limited. I am in the process of putting a Woods 22 XE cam in it. That should liven it up a bit. I have had ZERO problems with this bike from day 1.

Another proud 2020 owner here. 235,000 miles and the only time it's seen the back of a trailer is when it was delivered new to the dealership.
