2001 Chevy S-10 Burnt transmission or something else

I ran off the road into a yard during a snow. A few days later after being pulled out the track will go through all of the gears but if I give it more than about half throttle it bogs way down and loses speed. If I back off of it a little it will start to pick up speed again. It also has a rough shake at exactly 20 to 23 mph, before and after that it is smooth other than the bogging down.
