I have just done my Ford Maverick 22 2.0 AWD transmission fluid drain at 15xxxmiles. I did my rear "diff" and front ptu at 13k. I HIGHLY recommend people doing the ptu and diff immediately. Both on my truck were low on fluid. (0.7qt vs 0.9-1qt to fill) and the rear diff drain bolt had a thick film of metallic debre from the magnetic catch. ( I drive respectful, and towed a small boat probably 1xxx miles of the 13xxx (1,000 pounds of people, boat, equipment).

The transmission fluid change is actually easy.
1. Remove engine carpet/ undercarriage cover. T30 screws
2. Open up engine hood, remove air filter.
3. Find transmission cap. ( It will be a black rubberized cap with a red triangle on it.) *Location is just left of your battery* take cap off, it pulls right up.
4. Remove drain plug. (14 mm bolt)
5. Wait, take pride that you saved money doing yourself.
6. Re attach drain plug. (14mm)
7. Measure amount you removed. * I used a kitchen measuring cup (my cup could go to 3qt, so I measured, drained into a oil container, repeated till drain pot empty)
8. Add the amount you took out back in.
9. Start Maverick, 5 seconds in each gear. P,R,N,D. repeat going back to park. D,N,T,P. Go for a 15 minute drive, or enough to heat everything up for a bit. Keep Maverick on, in park after completion.
10. Find level plug on driver side by tire. Can get to by cranking wheel, or Remove tire. ( Remember to keep vehicle level if removing tire/ put back to level. Measure from floor to a trim line.)
11. Level bolt is a 10mm hex. It is about a foot into the wheel well. It will be next to a sticker that says "ULV mercon -_+2+'8+2w';#" (I can't speak engineer)
12. Remove bolt.
13. Allow excess to drain. *Keeping engine running while this is happening?* ( If someone disagrees, please verify.)
14. Once it is level, re attach drain plug.
15. Post on a Maverick forum for others to say you did something completely wrong and then consider if you broke your truck.

Thanks for your time guys n gals.
Awesome post. Thank you. Definitely a good enough procedure for doing it every 30k.

Pretty sure its the A cap from videos I've seen. Hard to say for sure, but chances are, there is only access to one of them, as mentioned above, next to the battery.

I made a post with the directions from the service manual here

I wanted to avoid confusion and start a new thread for anyone looking to do it the way FORD specifies instead of posting a "how to" on page 3 or 4 of the multiple other threads on it.

I would like to do mine at 60k miles. Has anyone done it and can you post a Step by step instructions or can you recommend a How to video?
The maintenance on a hybrid eCVT (transmission) is totally different.

Why can't you just fill it using a pump and the leveling plug instead of dismantling the air box?
Suppose you could as long as you have the right hose clamp pliers, but it's definitely easier removing the air boxes 3 (maybe 4) screws instead.

AFAIK the current government quotas are only for about 67% EV production by 2032....
Which is why they're going to have to build a lot more coal fired power plants in order to charge all those batteries... LOL.

I noticed from the manual that it suggested a 30,000 Mile interval for transmission fluid changes under severe service. And a huge interval over 100,000 for "normal" highway commuting. Which makes me believe that 30k is the real interval for people who want to keep it past the warranty period.

I'm a long way from 30k on my Ecoboost.

But I'm curious if anyone changed theirs already.

I did some casual research and couldn't find any videos on YouTube but I'm not sure what other FMC vehicles the eight-speed transmission is used in, figuring the drain and fill procedure would be similar.

Just curious if anyone's done it (or had someone else do it).
I changed the transmission oil on my 2023 tremor with the 8F35 at 34,000 miles and it looked terrible, so I ran it for 100 miles and changed it again, it's not burnt but very dark reddish brown. I'll change it again at 50,000 for sure because you can only get 4 1/2 qts out which is only 1/2 the oil at 9 qts total.

I'll personally be doing 30k intervals, I had a 6F35 in my '14 Escape and did 30k fluid changes and I had no issues with it and sold it with about 150k miles on it. Unfortunately the 8F35 does not have a serviceable transmission filter unless you want to split the transmission case open.
I changed my fluid at 10,000 miles and replaced it with AmOil. I did find a YouTube video which made it easy. You have to remove the left front tire to get at the fill plug. The truck must be level when you start the engine to see if fluid comes out of the hole. If not put more fluid in until it starts dripping. I love AmsOil for engine, filter and transmission.
