Will not start
Well that's not great because fluid coupling in the transfer case can spin the transmission by the output shaft if the transmission isn't in park, and without the transmission fluid pump operating it can overheat. But while there is the potential for damage none may have occurred, no way to know until you can drive the vehicle. We will still need the info requested in post #2 before anyone will be able to make constructive suggestions.I should have read the manual for flat towing.
I put the transfer case in neutral and the auto trans in neutral. Towed two hundred miles. After towing I moved auto trans to park and tried to start. No luck starting
You will never hear it "try to start". It either will or it will sit there. You don't start it. You send a signal to the computer that you wish to start the Jeep and if the computer agrees, it will start it. No cranking, cranking, cranking any longer. When my battery was going (almost 4 years old on factory battery) it would give me what I called a half start. Instead of the robust start where the RPMs ran up and then fell back to idle, they would stop at about 500 RPM and the engine would sit and chug with not throttle response. Most of the time a second try got a good start. Then one evening it took me 3 tries. I replaced the battery and no more issues for the last 18 months.2018 JL, Four door unlimited. Battery was mostly drained when I tried to start. Dash indicated, service trans, airbags. No sound of starter trying to engage. Thks
Nope, the transmission should not be in neutral for flat towing, only the transfer case.As someone else stated, I would definitely put the transfer case in neutral as well as the automatic transmission. With both in neutral, it should make any problems less likely to arise.
As @smiller1 said in post 5, putting the automatic transmission in neutral while flat towing can lead to the transmission output side being spun through a fluid coupling in the transfer case. If the internal parts of the transmission are spinning without the transmission pump pumping fluid, that can lead to damage due to parts spinning without lubrication.Does anyone know the reason it's done this way? Just curious.
