In the minority of times that my 2007 Camry V6 tranny doesn't slip (flare), it will hold in 3rd gear longer and to a highwr RPM before it shifts into 4th.
It reminded me of how my 2002 Camry V6 was, and I wondered if that's what it's supposed to be doing instead of slipping.
It got me to wondering...

One thing that initially came to mind months ago, was whether the logic thinks my tranny is up to temperature before it actually is, and lets the shift go ahead at the lower RPM like when it's warm? Because it either flares, or waits til a higher RPM, delays the shift and doesn't flare.
(This transaxle does have a fluid temperature sensor)

That's a good theory on things.

I know for sure when the cars overall temp. is warmer or warmed up, it upshifts at least 200-300 earlier than when cold. It would be nice to know what the behavior of others with trannys that don't have the flare like mine.

2 cars with identical programs, one car flares and and the other doesn't... seems more like a mechanical issue. The programming is a patch trying to fix it. But what's wierd is that with a new tranny, it still happens. So obviously there's variances in how trannys are built.
