Open Question: How do I disable the automatic downshifting in a 1991 Chevy Blazer?

It has a 4.3L V6 with automatic tranny with overdrive. Around here, people are terrible at driving, and so I'm constantly needing a boost of speed to "escape," per se. The thing is, this automatic downshifting thing is supposed to give it more power to speed up, but it doesn't. I press the gas to speed up, and it starts to take off until it shifts down and just suddenly redlines and slows the vehicle as well. Several times it has arrive close to blowing the motor. This even reduces the top end speed as well. Going down the highway, it's irritating because it downshifts every time I so much as adjust my foot on the pedal. So the engine is just going hummmmm RNNRNNRNNRNN hummmmmm RNNRNNRNNRNN hummmmm. It is terrible for that motor to undergo such strain, and that shifting is really getting annoying. Other people who have driven the car have said so as well- they try to pass someone and suddenly RNNRNNRNNRNN occurs. How can I disable that?!
