I just purchased a 79 cj7. Did not get to drive before I bought it. Just up and down a driveway. When I got it home and drove it noticed that when shifting into 2nd gear it jumps out of gear. No other problems with any other gear. It goes into 2nd smoothly but jumps out after about a second. Also sterring is very slow to react. have to overcomensate while steering. I am not very experienced with working on vehicles but want to learn. Any ideas please share? Thanks
