I've found that the trans will hold (not shift down) OD longer when NOT operating in the power mode.

I've tested this theory in conditions of headwind & uphill, & it's always the same.

With the power mode button NOT depressed, OD stays on longer.

How does your trans fluid level check? Not enough fluid can make for some valve-body actuations in an automatic transmission.

Ain't that what the power mode is all about ... makes it easier to kick down to a lower gear???
