Nah. That does not sound correct to me. I would think it is all about throttle position and RPM. With throttle closed and RPMs above maybe 1500, or perhaps 2000, I would think your car would slip right into DFCO. You might switch gears like that to raise the RPM above a necessary threshold but it is not likely a requirement that you be in D3 specifically.

I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.
