Several years ago I had a catastrophic engine failure while close to 600 miles from home. ended up towing it the first 160 miles with a tow strap, just to get back to civilization. The intent there was to rent a U-haul trailer to get it back home, but there were none to be had. Next best thing was to use a tow bar and flat tow it the remaining 400 miles. Throughout the whole ordeal, just towed it with the transmission in neutral. Did not perceive any damage to the transmission and/or differential. 5,000+ miles later and everything still checks out OK.

I don't want to do that ever again though.
