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.
have the same problem?

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