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.
