So I’m currently stuck at a gas station because my Jeep won’t move. I was driving along the interstate at about 65. Suddenly the Jeep made a sound and felt like something may have broke. Immediately lost power to transmission. I coasted down the nearest ramp and into a gas station. Transmission goes into forward and reverse and wants to move but something isn’t letting it. It won’t even roll backwards. First I thought the drive shaft broke but it is solid. I did check the transmission fluid and it is full and looks clean. I tried messing with the 4 wheel drive just to see if it made any difference and now I can’t get it out of 4 wheel low. The handle will not go down. Any suggestions would be greatly appreciated
