i have refilled/flushed recently and i was the goof that accidentally put atf4 instead of dexronIII/mercon in the tranny. it is still behaving well afer a second flush with the proper mercon the manual stated.
anyhow... the B2 code had me puzzled but everything else was been reset and has not thrown any codes today with several short trips around town and up/down hills and mountains.
the upshift choices this tranny makes seem just fine, the downshift choices with mine are odd sometimes too.
i guess the ECU had a hiccup or something.
again, thanks ozark and kluas for your help and experience.
cheers!
