If your tranny is dumping ATF going backward, or forward, you need to have your transmission completely checked out.

I just put a TruCool automatic transmission auxiliary cooler on my F250, and it was just a simple 25 minute job. At $150, it's the best insurance anyone can make to protect their $3500 transmission.

You need to take care of that 7.3 Excursion. They're no longer available and they're in very high demand in the RV world.

It only has dumped the fluid while towing if that helps.....that being said, I was in Tennessee camping when it happened. I stopped by the local Ford dealership to pick up a quart of Mercon V. While there I stopped and talked to one of the diesel mechanics and he said that he recommended one of these as a solution:

What do you think of the pan as solution?

Where did you get your TruCool?

Skip the pan and get this 32 row trans oil cooler from Rockauto for $180 (super cheap)....you can google the write up on how to do it. It is about 4 times bigger. I just got back from a trip to the mountains yesterday and the trans temp never ever got over 160 even when doing 65 up to the top of the Mogollon rim here in AZ which is a good pull at 7500 ft. It was my first trip with the new cooler towing my 7000 lb TT. Never got a chance to test without, but towing on the highway it would get to 180 on the flats with OEM cooler. Now towing on the highway it is 140. In the city it gets up to 165 with the AC on full blast and 110 degrees outside with TT.

Not towing it does not register on the gauge on the highway.
