that is easy. Throttle positioning sensor

I own a S-10 and they have a cable that runs from the throttle body to the transmission. This cable is off, broken, out of adjustment, or the valve it attaches to inside the transmission is sticking. Check this cable. Have a friend hold the accelerator to the floor, and see if you can pull on the cable to make it move any. It should move a little as in a 1/16 of an inch. If it moves any more than this, then it needs adjusted. With the throttle relaxed, look to see this black horse shoe shaped lock where it connects to the bracket that retains it. It is part of the cable, and is just behind the bracket and on the top. Use a small screw driver to pop it up and you will hear the cable snap free. Now push this lock back down to the lock position again. Place your foot on the accelerator, and stomp it to the floor all the way. You should hear a zipping kind of sound as it adjusts. That should fix it. Another way to do this is unlock the cable, have a friend hold the accelerator to the floor, and grab the cable and pull it just a very little past being tight and lock it in that position by pushing the lock back down.
If this does not fix the problem, go to Advance Auto parts store and get a bottle of Lube-Gaurd in the white bottle, or the one that is made for an American vehicle. This is some good stuff, and will unstick most valves in a transmission. We used this stuff for years, and we used to call it transmission rebuild in a bottle. Its some very good stuff, and WILL work. I own a transmission shop, and I have seen this problem many times with a 700r-4. They are bad to do this. If you can't get it to work right, take it to a transmission shop, and they will adjust the cable for you, and most wont even charge you to do it, as it only takes a minute to do it. The only tools you need to do it with is a small straight edge screw driver.
Glad I could help you. Good Luck!!!

You should have an engine light on too! I would have it checked. The computer also controls shift timing, and will make the transmission shift hard if a problem is detected.
Your vehicle is to new to have a vacuum modulator valve, so checking it would be a waste of time.
Either way, I would have it checked out as soon as possible. The longer you put it off, the more it's gonna cost when you decide to get it fixed.

Your transmisson does not have a modulator. It probably has set a trouble code of some sort. Many transmission trouble codes will command maximum line pressure causing it to shift hard. You need to have it checked for codes even if there is no check engine light.

My car was doing that too. I had my check engine light on. It was the Mass Air Flow Sensor.
