Changed the eCVT transmission fluid in my Hybrid Maverick

[72Maverick]

After reading about 4WD PTU units being underfilled from the factory, I decided to go ahead and change the fluid in the eCVT yesterday. I have 14,000 troublefree miles and was doing my third oil change at the same time while I had the splash shield off. I found a couple of things I was not expecting.

The 14 mm drain plug for the eCVT was a lot looser than I was expecting. It wasn't finger tight, but took very little effort to turn with my wrench. It does have fine threads going into an aluminum housing so I was careful not to overtighten when I replaced it.

I drained about 3 quarts of fluid (shown in the 1 gallon jug photo) and refilled with 4 quarts before it started to run out the fill plug hole. I believe it was slightly underfilled at the factory. Probably not enought to damage anything but still a little underfilled.

The fluid was darker than I thought it would be, but didn't smell burnt or unusual. There were a few metallic flecks in the pan, but I expected that.

Overall the job was about as easy as doing an oil change, especially with the splash shield already removed. And the peace of mind is worth a little to me since I plan to keep the truck long term. I plan to wait another 30K and do the drain/fill again.

How did you fill the transmission? Hose, funnel?

What's everybody changing their oil at after purchase for the first change?3k?5k?

Easiest way is to jump pick up a pump attachment for bottle

I used a hose and a funnel I made for this kind of job. You could use a hand pump, but that's a lot of pumping to get 4 qts in there.

I have one of these I use for filling my boat lower unit and the differentials on my Expedition works great. It won't fit the larger openings on the Mercon containers so you would have to transfer the fluid to a regular quart bottle. Then pump for a while to get 4 qts in there. Just easier/faster with a little hose and funnel.

That seems like an excessively short eCVT fluid change interval, given that (a) the manufacturer specified the first change at 150k miles, (b) its essentially just a diff and not a tranny with clutch packs and overheated fluid to wear out, (c) people who have changed it report that the fluid is clean with essentially no metal in it. Unless its been in a flood, I think I'd believe Fords recommended interval in this case.

It is a SUPER SHORT and no way needed transmission oil change interval.

2005 eCVT (generation 1) had LIFETIME oil in a sealed system.

I think Ford now recommends changing at 150,000 mile intervals.

OP's truck is a Hybrid. Yours is an ecoboost. Oil change intervals are different for each because the Hybrid's ODO reading is much higher than the miles on its gasoline engine.

A search should find TONs of threads on your question for ecoboost owners.

I plan on doing mine at my next oil change at 35,000 miles. I use Amsoil in everything I have and use their EZ Fill QTs. Its basically and thin plastic paper like container that you can just squish all the oil out of, it works quite well. I will do it again at like 70,000 miles.

I did my first oil change at 1,500 miles, next one 3,500 miles later at 5,000 and every 5,000 since. Never has used any and OLM never went below 50% oil life left. Almost 35,000 miles and no problems.

Not due to the excessive oil changes.
