My Ford E350 running a bit hotter
I recently had one of my cylinder heads rebuilt and a new exhaust manifold installed, as well as a new radiator and thermostat - just got back from a trip to Colorado and there were several occasions ...

The E4OD is famous for puking out tranny fluid after a hot run and then being required to push a load in reverse, and even more so if it is being backed uphill in those conditions.
I know. I've got one and done that. It's a mess.
That's the bad news.
The good news is that unless this has happened a lot or it's just getting too old and worn, the tranny is normally OK after it cools off and the lost fluid is replaced. The seal that lets out the fluid recovers and is good to go.
I use normal tranny fluid in mine, no special synthetics or anything.
A couple of years ago I installed a larger Tru Cool auxiliary tranny cooler in place of the tiny factory one in front of the radiator. The larger cooler has brought the temperatures down a lot. If you install one, be sure to keep the factory-designed tranny oil flow path that sends oil through the bottom of the engine radiator first. The cooling effect from the radiator coolant is important to the overall cooling capacity of the transmission.
