Decided to go away from the office for lunch today and jumped into the jeep and fired her up. When I tried to shift into first gear it wouldn't go into gear, 2nd, 3rd, 4th or 5th wouldn't work either. I tried to get it to go into reverse and just got a bunch of grinding. After shutting down the engine and putting it into first gear and restaring with the clutch depressed I was back in buisness. All gears worked well and seems to be back to normal. The jeep is a 93YJ, 4.0L with the dreaded 5 speed Peugeot transmission. Has anyone ever experienced this before? I am worried this is a omen of things to come. Thanks, Frank
