Might try disconnecting the kickdown microswitch --one of the two that are
actuated by the throttle spool at wide open throttle. The other one cuts off
the A/C compressor. Unplug both if you can't easily tell which is which.
There's an inline connector a few inches downstream from the switches; just
separate them there and drive the car. If the switch is the culprit the car
will now drive fine, but won't downshift when you floor it.

The switch is supposed to cause a 3 to 2 (or even to first, depending on
vehicle speed) downshift when you floor the accelerator. I've only seen one
of these switches fail, but it caused erratic downshifts when cruising along
in third, ocasional strange upshift points, and some second gear hold
problems. Worked fine when it was cold. Longshot, but worth a try.
