2012 F150 6r80 fluid change
Hello,
I used search and google and it appeared no one has changed there Fluid in the new transmission yet.
Today I change my Fluid and "Screen". I say screen cause that is what Ford is calling it.
I have pictures I will post at a later date when someone shows me how LOL.
My truck has 42,XXX miles on it. I have pulled my 31' TT around for 3500 miles total weight is 12600. Heavy. The rest of the miles were long comutes and getting out of dodge.
I used a 19 mm wrench for the fill plug and a 8 mm 1/4 inch drive for the pan bolts. The pan has a reusable gasket. 4 bolts are tucked under the exhuast and I had to use a boxed in wrench to get them. All the fluid likes to drain out the back pouring over the exhaust. No biggie just thought I could make a smaller mess...
The Fluid was very dirty. It did not have a heavy burn smell. The magnet had a couple good sized shavings/ chips on it and very little buildup. I am glad I changed it when I did.
I bought a motorcraft screen and filled it up with Valvoline LV. I could not get anything to drain out of the TC so I only changed the pan. 6.5 Qts. There are two types of screen pickup lengths. A 1"and a 1.5". Mine took the 1". I guess there is a deep pan or one for the 6.2L uses a deeper sump?
So if anyone is itching to change it go for it. I was hesitant on changing it but my common sense said I should. I am very glad I did. My tranny was not acting funny or shifting slow. I just figured after that many miles on original fill it was time.
Again I will post pics later.

did mine at 75k miles. also used the lines at the cooler to completely change the fluid by pumping int out. started coming out clear at around 14 liters of fluid. running a magnefine filter now to keep it as clean as possible.

Took pictures in the sun to show how dark it is. Also the magnet. The blurry pic is the stamping on the filter. says inlet 20.5mm and below it 8.0mm.
New filter I just got today says two inlets and one has crude stamp of a single inlet and a double..... left me confused LOL
The only thing I have not changed yet is the T-case. this weekend I hope. Hope this is a help for others.

Now that you've changed it once and can verify that the transmission filter on most Ford products is indeed a fine wire screen. No real need to change it. Install a pan with a magnetic drain plug. When changing the engine oil, verify the trans fluid is bright red. If not drain it also. Using a drain plug is the simplest most affective method for auto trans maintenance. The soot and debris is always at a minimum, not being left to build up.

This is the method that I usually use. How did you do it with out a dipstick and fill tube? I think I am going to have to order an aftermarket fill tube/dipstick to make this job much easier.

with difficulty
The dealer dropped the pan and changed the filter while replacing the bulkhead electrical connector(common leak point on the 6r80). The invoice showed 5 liters of Mercon LV replaced so it still had a lot of old fluid in it.
I pulled the upper hose from the cooler and found out which way the fluid flows, then attempted to run the engine to pump out the old fluid, while sucking fresh fluid from a second container. That failed because there is a thermostat on the cooling system that will not allow fluid to be sucked back in unless it is above 172F (i think that's the thermostat opening temperature).
I then pumped out 2 liters at a time and refilled the pan with exactly 2 liters via the dipstick port under the truck using a funnel and hose. It took a long time to get through this procedure enough times to start getting clear fluid out of the cooler, 7 to be precise, but I wasn't in a rush and it worked out fine.
As a matter of info, the fluid pumps out of the upper barb (right, driver's side) of the cooler mounted up front (this is still the same on my 2013 5.0l work truck) with the engine running, but will not draw fresh fluid in unless it's fully hot. The hoses are all 1/2" inside diameter and a 1/2" magnefine filter will work just fine on the output side of the cooler.
