the new normal...
Please change the ATF before you add Lubegard Red or anything else.Given that it was running perfectly coming into service and ran like crap coming out of service (and that the old fluid look just like new coming out), I don't think it's a pressure switch problem but more of the fluid problem.
Thank you odyfamily.
I also ordered Lubeguard red to try out.
Sounds like you are getting closer to solving the problem.The ATF looks good on the stick, good level checked while hot.
It is a single drain-fill
He changed ATF for me before (I let him change it on Honda schedule for documentation, I change the ATF myself for every A1 as a "silent" service just for my piece of mind). Everything was OK the last time using the same fluid as this time.
One thing I didn't mention was that during the fill, he spilled some outside and made a little mess so he sprayed some cleaner and water to clean the front of the engine. I do see some fluid remain on the electrical connectors. I don't know if this could cause problem. I was more worried about getting the VCMMuzzle2 connector wet because I'm not sure if it is made to the same standard as the rest of the connectors. I think new engine can take a little water hosing without problem but I never feel comfortable doing that myself.
dick, you might be talking about a different transmission design.The PCM will continually "learn" to a low but finite slip RPM target. This is to shed pump loadcaused by more head pressure than absolutely necessary.
