Wow, it's been so long since I've worked on a car with an automatic
I didn't know there was a Dexron III. There are two types of auto
xmission fluid, Type F for Fords, and Dexron for everything else.
I can't imagine that III wouldn't be backward compatible with II.
But your problem might not be the fluid (if you're lucky...). An
automatic "knows" when to downshift in a couple different ways.
Usually there's a lever attached to the carburator linkage (yeah,
I'm dating myself here) that lets it know when you punch the gas.
Also a vacuum line can tell it the same thing. Sometimes the
vacuum like gets blocked or the rubber diaphragm on the "switch"
inside the transmission develops a leak. I know zero about the
engineering of Japanese cars, except that they've always struck
me as a little eccentric, so YMMV. Hope this helps.
