My wife was cruising along on the freeway in 5th gear when the engine starting revving up and the Jeep started slowing down. She pulled over and couldn't get the Jeep to go anywhere. Upon further messing around, we discovered that she has no gears except 4th gear. In addition, you can switch the gears to any other gear except for 4th without the clutch. This includes reverse. Fourth gear works just fine. You can push the clutch in and as long as you feather the clutch and give it enough gas, you can get it moving. This is a 93 Wrangler with the AX15 transmission. Any ideas anyone?
