I took the tower off, no rust. I cannot determine anything. But the IN / OUT for high and low is stuck and I am stuck in low. The Jeep runs and, drives fine, I can shift through the gears, but at this point, I am stuck in low. Yesterday when I drove it and parked it I noticed a large puddle of watery oil. I thought when I drained the transfer case that would include the transmission.

I stuck my head under the jeep and find the transmission drain plug is missing, located at the very bottom of the transmission. I searched around where I drove and did not find the drain plug. I have never taken it off. But there is probably no fluid left in the transmission.

New question, Will the transmission fill plug part number 5140A fit?
