I pulled the skid plate off my jeep because I am trying to figure out where the transmission fluid is leaking from. I suspect its from the rear main seal, but I cannot tell for sure because everything is gummed up and dirty under there. I can't clean it well with the skid plate on, so I removed the skid plate, cleaned 'er up and now I would like to leave it off until tomorrow night so I can assess where the leak is coming from and how much its leaking. Would the tranny and transfer case be ok without being blocked up? I'd like to leave it free and clear with no blocks or jacks get in the way of the drip to be sure I can figure out where the leak is coming from.
