2016 DCT US Stalling, holding gear too long, Chugging

[mzflorida]

I posted last week that I had an issue with my 2016 DCT shutting down and having no signs of life after accidentally putting the kickstand down while in gear, in the garage. It corrected itself without intervention other than waiting.  I changed my oil, DCT filter, oil filter, and final drive oil.  All original honda parts and fluids.  Oil was filled to specification ( 4.2 us quarts on engine oil..honda GN4 and 7.7 oz on final drive oil...also Honda).  I was riding today in D mode at about 65 MPH.  The bike was in 6th.  All of a sudden the bike felt like there was just barely enough power for the gear...like a manual transmission...chug, chug, chug.  It corrected itself.  Then it did it again.  I could not accelerate.  It corrected itself again.  I went on the back road and it did it three more times, but this time the engine died.  It did seem like it was holding the gear too long after I got going again.  I have not completed the DCT initialization procedure as recommended by another member, yet.  Any ideas on what could be causing this?  I am planning on a 500 miler in the near future and want to make sure that it's in great running shape. 

I did check the engine oil.  It seems like it is just slightly overfilled...just barely, maybe an ounce or two.  Could the fluids change be related?  Should I be looking at other areas?

I did notice one other thing early in the ride.  While navigating a curve it felt like it came out of gear altogether...you know that feeling when it feels like you are on ice?  But there were no indications of that actually being the case as when I accelerated it responded to the throttle.  I did allow the DCT to shift for me in the curve. 

Thank you in advance for taking the time out of your day to review this and offer any advice.

Sorry mate, ive been on this site nearly 6 years and never heard anything like this before.

Thanks, Hartley.  As always, appreciated.

Looking at the manual.  I am leaning toward the HISS or the ECM in general.  I appreciate any input.

It is possible for engine oil to be sucked into the crankcase breather tube if the oil level is too high.  When that happens, the oil often ends up saturating the air filter element.  That will, in turn, starve the engine of air.  You might want to take a look there.  You might also drain a bit of oil to get the level corrected.

One of the best ways to diagnose problems is to eliminate other possibilities, one at a time.

Best of luck.

Thanks, Spud.   I'll do that.   And as luck would have it, my air filter replacement arrived here at home.  Thanks for the well wishes on diagnosing and resolving this....and for the advice and insight.  Mike

US models does NOT have the HISS system.   HISS is the key immobilizer anti theft system.  Also know as the “chip key” common to most new cars.

Odd things happening.......
First check would be battery connections and battery voltage,  several reports ( on other models) low voltage for any reason causing  running and shifting issues.

One or two quarts of too much oil might cause breather problems, couple of ounces will not cause a problem.

My suggestion is to reset the DCT - it's a no-cost 5 minute job and it made a whole world of difference to mine.  I did not have the issues as you state but mine used to change up way too early.  Reset the DCT and it's as good as gold now.
