I have a 2000 jeep wrangler sport. In the last year started having a problem with the Automatic transmission. It only happens when it sets for 3 or 4 hrs. You go out start it back it out of the driveway then put it into drive and it acts like it dont want to go, then all of a sudden it catches and takes off usually after that it does not do it anymore during that time off driving. Seems like the colder the weather gets the more often it does it. If you have any insight it would be greatly appreciated.
