Automatic Transmission Shift Points

#3
I am trying to save gas, and want to know, at what speed, or rpm does my automatic tranny shift up from, 1-2, 2-3, 3-4th, or overdrive. Say the car shifts from 1-2nd at 11mph, or 2100 rpm. I can let of the gas, at 12mph, the car will shilt into 2nd gear ( a higher gear) and my rpms will drop, and I can still pick-up speed , but save gas, from the lower rpms.

I have a 3 speed, but what i can tell you is, just use common sense, dont let it rev up really high, and you should be fine. Also what helps me to keep the mpg and ponys high, is keeping your fluids fresh, your tires air up right, and tuneups.
hope that helps
