    Auto won't kick down up hill

    When going up hills the Auto (2001 GU) does not kick back to 3rd even if the accelerator is fully depressed. Taking my foot off the accelerator and then putting it down again, the auto will select 3rd hitting about 2500 RPM but always then changes to 4th about 2-3 seconds later. I have tried playing with O/D both on and off and also the A/T Hold Power Switch without success. Not sure what I need to check, Auto or ECU or something else?

    Not sure if it's fluid related but how long since the tranny was serviced?

    Perhaps a blockage in the valve body?

    These transmissions are not very smart and tend to avoid downshifting until most power is lost.
    I have always found it easiest to drive in manual mode when this becomes an issue

    The auto only has 1st & 2nd manual gear options. I was doing some more investigation, is it possible the Throttle Position Sensor is the problem? I am not sure as the problem mostly occurs up hills.

    Yes, I have an O/D button. But I do not understand what it has to do with my problem.
