Transmission won't shift into high gear until fully warmed up

1994 4Runner, V6-3.0 2WD Auto 3VZE
Typical scenario - This started a few weeks ago - Start car, around 2 miles to freeway entrance, take freeway 6 miles to destination, at 60 MPH, engine speed is around 3100 RPM. 20 minutes later on the way home, at 60 MPH, engine speed is just over 2000 RPM. Transmission was drained, flushed, filter replaced and refilled a week ago. Of course the local transmission shop recommends replacing. Any ideas would be greatly appreciated.

If that transmission is anything like other Aisin transmissions of the era, that's normal behavior.

On gen3/4 Camrys the A140E or A540E/A541E don't shift into overdrive until warmed up.

Just make sure that the ATF level is full.

Toss in a bottle of Lubegard Red.

And, what ATF was used?

Make sure engine thermostat is working, or replace it if it hasn't been changed recently.

Monitor coolant temperature and you'll see the 'warm up' programming at work.
