Interesting article. I know you are on or ahead of the curve, what have you been using?
Thanks.

Not sure that I'm ahead of the curve but I have been using full synthetic since the late 70's. At first, I used the blend recommended by Ford but decided that the amount of weight we haul around justified the full synthetic.

I too use the the same and in tranny too
All the lubricants in our LD are synthetic. They are not that much more expensive anymore.
Mobil 1 5W-20 is less than $5.00 a quart at Walmart, so it isn't much more expensive than Ford's semi-synthetic 5w-20 oil.
Synthetic motor oil can be run longer than conventional oil, if needed.
Valvoline MaxLife Multi-Vehicle synthetic Automatic Transmission is $18 a gallon, at Walmart.
A total flush (20-qts) will cost right around $100. Cheap compared to the $5000 cost of a remanufactured transmission.
This is the fluid that our transmission was filled with when rebuilt by John Wood

Never even thought of synthetic tranny fluid. Mines due for a flush after my trip to Oregon next month and I think I'll look into this. According to records on my LD the original owner didn't flush and fill until 50k the first time which is a concern of mine so a little extra pampering at this point couldn't hurt.
