Is your tranny electric? If not I dont believe the ECU has any control. I recall valves internal to trans control it? I would post this in trans area or search "shift points" or "shift rpm".

sounds like your tv cable it messed up, or "kicked down" is not adjusted correctly

Here's the tech article on adjusting the TV cable. Here's another one, little bit better explanation.

Here's a picture... I added my own take on the directions as well. Hope it helps. (<-- That pic is from my 305 TPI, but the cable adjuster assembly should be the same on your car.)

Each of those three sets of instructions will get you to the same point, I just like to give multiple choices in case you might find one is easier to understand than the others.
