Re: 97 wrangler towing instruction & precaution

It is complicated but I will give it a try. The manual transmission is lubricated by the main shaft spinning the cluster gear. If the transmission is in neutral and the tail shaft spins the cluster gear does not spin and the bearings in the back of the main shaft are spinning dry. I agree with the idea that with the transfer case in neutral it shouldn't give torque to the output shaft of the manual trans. But the spinning transfer case gears have no resistance and could theoretically spin the input shaft of the transfer case. On my Jeep I put the transfer case in neutral and the automatic trans in park. Have been doing this since 1988 and never have a problem. I once towed a manual trans car 50 miles before I knew about the issue and the main shaft seized up and spun the engine.
