Tonight I was off roading with some friends and I had the clutch depressed, was giving it some gas, and as I was taking my foot of the clutch I slid off a rock. This caused me to accidentally give a lot of gas and drop the clutch at around 4500 rpm's.... The Jeep did not like this. I heard a bang noise and now my transmission will not engage. The shifter will move into the gear position but nothing happens. Please help and thanks.
