Transmission leaks when towing
This is probably not the place for this post but I'm curious if anyone has experienced this. My tow vehicle is a 2002 Ford 250, 7.3 Powerstroke diesel. I'm towing a 7000 travel trailer. The problem is...

My son has a 2002 F-350 dually 7.3 diesel. His transmission only leaks when he backs the trailer up a hill after towing home on a hot day--I believe it is the rear seal. That is the famous Ford 4R100 transmission which is not famous for reliability, as opposed to the 7.3 engine. Other son lost his at 100,000 mi. First son decided that it was cheaper to fill the fluid occasionally than pay for a complete rebuild before it goes out completely--has been running this way for over 50,000 mi. Most Ford transmissions are not hurt by overfilling--they just blow it out the breather--still best to properly fill. As said above, need to find out where the fluid is coming out. Best advice would come from an independent, non-chain, transmission shop.
