I have a 2001 Chevy Trail Blazer. When I go over 10mph the car jolts once really hard. Any other speed it seems to be fine. Also I don't know if this is related but I noticed the 4WD feature is engaging, even if I switch it back to 2WD it just automatically goes back into 4WD on it's own.

Check for power to the 4wd actuator on the transfer case. Chances are there is a problem there.
