E450 1st Transmission Oil Change?

My 2008 manual says 30,000 miles in RV Service. The higher mileage numbers are for vans and pickups. There is no time change specified. My 08 has 17k miles and I won't be changing it until 30k. At that time I'll put synthetic in. Synthetic in the tranny is the only thing I ever did that improved mileage - not much, but measurable.

The manual says there is a long life coolant, good for 100k miles in vans and pickups. In RV use that is reduced to 60k. No time specified. In my 2000 V-10 coolant flush and change was every 2 years. Must be a different chemical make-up of the current fluid. The stated reason for the 2 year change on the 2000 was due to different metals: aluminum heads and steel engine block.

I just signed up for the FMCA Rally at Madison, WI at the end of July. Hope to find a Ford engineer in one of the booths and pin down some numbers.

Will take about 8 qts of Ford LV tranny fluid and a change out of the internal and external filters.

This is a great vid.

Torqueshift fluid and filter change

Takes me a couple hours labor.

Good video. That guy is a character! He mentioned 40,000 miles on the changeout of transmission fluid. I guess that is what I need to consider, and maybe not years?

If you have 5 years on it I'd probably just change it out anyway. More than likely all is good(it is a REALLY stout tranny) The few hundred dollars it would cost would be worth it for the next 5 years.

It's a 2009 Ford E450 on a 2010 Itasca Cambria RV.
