Transmission fluid and other fluid intervals for AWD

[mavhopefull]

I couldn’t find it but could anyone show me a post of, other than engine oil, what fluids need changing and at what intervals? I have a AWD 2022 eco boost.

I posted a few videos about the topic here: https://www.youtube.com/channel/UCF0Id6LKrPKm6TSddr4g8wg


I replaced the PTU and RDU at 15,000 miles, followed by the transmission at 30,000 miles. Since then, I’ve been following the severe duty maintenance schedule, replacing the PTU, RDU, and transmission fluid every 30,000 miles. I also use Ford Brand Fluids for these.

Engine Oil, I change every 5000 Miles.


I hope the videos are helpful!

Yes, the last sentence was sarcasm. Sarcasm detector down?

You know the sarcasm was on point when they have to ask

I'm pretty sure it's supposed to be 6.02 * 10^23 miles . . .

This is the way...
Except I try to get the oil changed out between 4000-4500 miles and I'm holding off on the PTU and RDU fluids until the weather cools off, which should be around 23000 miles. I might do the trans at the same time since it is over 2 years now. After that, it will be 30k interval for all three.

Don't forget the blinker fluid!

Every 6,521 miles, whether it needs it or not!

Good Lord man! Do you want his car to fail? Every 3750 miles on the blinker fluid and not a tenth more!

I don't worry about the blinker fluid. I had all my accessory circuit, main harness and hybrid system electrons taken out, polished, blueprinted and ceramic coated, they can't wear out now.

Thought I would post my 60K update here... for those who are interested.

Along with my regular service, I also changed ATF for the second time, first at 30K, fluid looked good, just a little darker than new, so I will continue at 30K intervals.

Did the PTU & RDU for the third time, first around 15k, second around 30K, and now at 60K. Happy to say both looked just like the new oil, very clear, not much debris on the drain plugs. So I will push the next one out to 100K.

Front pads still have plenty of material, rears are probably about 10-15K away from replacement. Overall, underbody looks great having gone thru 3 salty Ohio winters. No leaks, very little rust, very happy how everything is aging.
