Hi Melsman (or anyone),Here's another point on oil - oil and water normally don't mix very well, but they will emulsify when pulled through an oil pump rotor. And the Hondamatic tranny really doesn't like to run with salad dressing in its innards. So if you like to play submarine captain with your 400 AT, be sure to check for water intrusion into the oil. If you suspect that water has gotten into the oil, don't take the chance - flush it/change it!
No kidding eh, these freakin Hondamatics are such a pain! Glad you figured our your issue. Mine was a code 12 (also stuck in limp mode) did all the testing in the manual, determined it to be a bad shift motor circuit in the ECM. Created a workaround to make it work without needing the ECM. Saved 200$Hello guys hope all is well. I registered just to help anyone with the dreaded 6 blink error code and the stuck on a gear doesn't shift to the next gear and when you put it in reverse it sputters. All are related. After searching the web for 4days and no final solution being posted I figured it out! I did a mixture of things. I wont bore you with the stuff I did with no success I'm just getting to the point. The "FIX" I took apart the autoshifter motor cleaned it up and re-lubed the rear resting point and bearing, on page 24-24 in the Note it says (NOTE: The ball nut of the automatic transmission unit can strike the shaft end and lockup. This is just a temporary symptom. In the case, be sure that the motor shaft joint turns smoothly after releasing it) This was the cause of all my problems even after new sensor purchase. I taped on it and moved it, pulled it with pliers. I changed the Angle sensor and installed it a the manual states (keep in mind, when u install it you have to mount it to the small bracket then align with the flat metal rod and turn to around 2oclock softly youll feel like a small spring type tension). After that I did the initial setting procedure outline on page 24-9 on manual and it was fixed. keep in mind, this writing sounds easier than the mission I went on doing electrical diagnosis and all. This is to the point and literally the fix!
Clutch will slip if the oil in there is not spec'd JASO-MA or MA2 or says safe for wet clutches. If in doubt, change it, run it a bit, change it again. But damage could already be done. Or oil could be fine and clutch could just be slipping, and needs to be replaced.I just read this and it is an awesome write up with some great info! My problem is exactly as you described, in auto mode the bike bogs down, in ESP I have no issues at all. You mentioned that it is the clutch slipping, so there a fix for that or do I need a new clutch? I'm not sure on the oil that's in there, brand specifically, would changing it out to the way you do your oil possibly help?
Thanks in advance
