I was wheeling my '89 4 runner this weekend, nothing crazy just on a basic trail, trailing my buddys on their bikes and 4 wheelers. I start going up a switch back in 4 low with my manual hubs locked and me engine bogs down so i let my truck roll back down the hill. Once we get it to a stopping point we try and go back up and there is no power to my wheels what so ever. My clutch pedal feels soft and i can switch to any gear at any time, car on or off, without pushing in the pedal. The transfer case is also stuck in four wheel drive. The transmission is spinning but no gears are catching what so ever. Any suggestions?
