I believe I have figured out what was causing my intermittent Battery system fault > Transmission Fault issues that started recently. So, this thread is just to put out what I believe should fix the issue. I did do some searching and this fix was mentioned, but I wanted to title and tags to be specific to help out future searchers.
Issue:
-Intermittent "Battery System Fault" that quickly goes away to be replaced with "Transmission Fault"
-"Battery System Fault" sometimes comes back on after going out
-Bike enters limp mode and QS stops working due to "Transmission Fault"
Temporary Resolution:
-Turned the bike completely off and then back on clears the "Transmission Fault". QS works and limp mode gone.
Final Resolution: (Hopefully)
-Checked battery terminals. Both were tight. This DID NOT fix the issue. REMOVED battery and checked busbar connection on positive terminal. See images for what I found.
-Busbar connection was very loose. Screw was bottomed out and still not securing the busbar to the terminal post. Used bolt nothing like the shorter, locking bolts on the two easy to access terminals. I don't know if this random bolt is the correct one, or the dealer was just stupid when they installed the battery. I used the two locking bolts on the terminal posts and the longer bolt on the busbar where depth isn't an issue.
-I have yet to ride since finding this, but the CEL is already gone. I'll be quite surprised if this DOESN'T fix it. What I don't get is how it took 1400 miles before this issue started when that thing has been loose since mile 0...
Anyway, if you get the above errors, checking the battery posts is easy if you live 2 hours away from the nearest dealer.
