Gear oil for trans and rearends

[Johnboy]

You most certainly can run them in neutral for short distance, as long as they are in high range, and the engine is running turning the pump inside the transmission.
In a towing situation this is no different than going down the road.
That in neutral damage happens when the oil is not being pumped It frys the back section of the transmission. If that statment were true wouldn't it mess up all of the cars you see towed behind an rv. And yes I know they are modified to do so with transmission lines from the rv itself to flow the fluid. I understand what you are doing rawze by going to neutral that takes some skill and good timing to do so.
