Is the the traction control doing it's job. I don't mean to be insulting, but folks that haven't dealt with it are sometimes surprised and think something is broken. I had a guy I work with take is jeep into the shop 3 times for transmission issues. He finally took me for a ride to show me the problem and it was the traction control. He pushed the "off" button and it suddenly quit having the problem. Good luck and let us know what you find.
