Both fluids should be Mercon V. Power steering I changed soon after purchasing the car in late March; transmission I don't know when (if?) it was changed.

Note the difference in color.

My question: do non-Motorcraft fluids which meet or exceed Ford/Motorcraft specifications have the same color as the original Motorcraft fluid? Or do the specifications not include the color?

The transmission fluid is simply a more pale shade of red/orange (could that be the color of Mercon prior to Mercon V?).
It does not smell, and if you look at a drop hanging from the dipstick, it's entirely translucent (not milky, dark or opaque).

One way or another I want to replace the transmission fluid as soon as I find a place where I can do that. Just wondering if the color could be a clue as to what fluid is in there currently.

The transmission fluid is just older and dirtier. Not dirty enough to be worried about it, but the color difference is just from it being older.

MadMikeyL is right. Only other thing to say about trans fluid is that in order for the bottle to say Mercon V on it. It has to meet all the specs of that fluid. Same goes for the other types of trans fluid. Probably a good idea to do a fluid and filter change.

And drain the torque converter during the fluid change. A full fluid change is 12 qts total.

I know the Valvoine MaxLife ATF is labeled as compatible for Mercon LV, but not V. I used it for a while in my cars but I started getting the Motorcraft Mercon V. I'm on the fence about it. :unsure:

That will be fine. Pretty much any bottle that specifically says MerconV will work fine, regardless of brand.

I've used the Castrol Mercon V for years; Anything at walmart is way cheaper, lol.

I've gotten several different brands. Motorcraft oil was the same price as the others when I got it, not twice as much, lol! Try Amazon.

Transmission fluid is required to be red; PATC had trouble from the regulators for selling their bright green "raptor blood" fluid.

Is it different for the Euro cars? I've seen plenty clear and brown fluids for the Euro stuff.

Not to mention the blue Mercedes ATF!

This was ~10 years ago; it apparently was won by Patc, and it can be any color now. I can't find a link to it now...

A thought...hear me out:

In a perfect world, I'd drain my transmission pan and torque converter and cooler lines. But I don't really have the space to do that right now. So why not do the same I did with my power steering?

With the steering, I simply siphoned out the reservoir, replaced the same amount of fluid with fresh Mercon V, and repeated this process after each drive until the quart of fluid was used up. The result is fluid that becomes gradually cleaner.

I could do the same with the transmission: siphon out through the dipstick tube (maybe what? 1-2 quarts per application?), replace with fresh fluid, and repeat.

Has anyone done this? How much can you get out of the pan with this method?

I'm sure it would work but it sounds like you'd use more trans fluid in the long run.
