Changing The Transmission Fluid on Your Hybrid Maverick (DIY Step By Step)

[Hardening2753]

Awesome write up . My 15' Outlander Sport Cvt 2 was every 30K miles. Drain 4.5qts, drop pan, replace mesh filter and most important: change the Cvt cooler filter. Of course that tiny little cooler filter got overlooked by many owners because it was buried underneath the battery tray and 2 brackets

Yeah I'm trying to figure out what the filter is for the Maverick. RockAuto has two listed and local auto parts have one listed but it looks like the EcoBoost and this one share a filter.

I've also been looking at other Ford models but I can't find a video of someone dropping the pan and changing the filter. If I can find a video of the transmission being open so I can tell what kind of gasket and filter it has then I'll do the pan drop next cycle

Assuming it's design is very similar to the HF35 (solid bet) the filter can't be changed unless you split the unit itself.

With the service life of these units, it's probably unnecessary. Changing the fluid regularly should be more than enough. There are no clutch packs to wear and contaminate the fluid. It looks like the biggest threat is winding failure due to the oil getting hot and attacking the copper winding coating and the fluid losing it's lubricating qualities and bearing failure.

Thanks for the pic! I'll start the comparing both and see what I can find

No point in looking. It's not a serviceable part.

I think you are correct. I looked around more and it looks like the family of HF35-45 you have to open the transmission completely to replace the filter

Driver side.

Thanks for this write up! I'm looking to do mine at 20k miles just to make sure it wasn't underfilled at the factory since I have seen that a few times here. After that I probably won't touch it again for another 60k.

Mine was underfilled slight

Has anyone found the actual torque values for plugs besides 1/4 turn more? Thanks

It's like 30ish pounds. The user Montana has a post for the EcoBoost version.

30ft/lbs? That seem very high for a plug in an aluminum case.

I think we are over thinking it. No one torque an engine oil drain plug which is also in an aluminum case. Just snug it up.

106 in./lb. on the drain. 26 ft./lb. on the fill/check. You will have a bad day if you strip the transmission case at the drain.

There is another thread where this is discussed. https://www.mavericktruckclub.com/f...ansmission-fluid-in-my-hybrid-maverick.47358/

Cheers.

I agree but someone asked for the torque and I remember seeing either 30ish or high 20s. I just snug it and go slightly past it

I did this recently on my 2023 Lariat Lux Hybrid. While Ford and other manufactures say some fluids are lifetime, that's just because they want to say that it is cheap to own a vehicle. Due to the driving style and conditions that the truck operates on I have to preform regular transmission drain and fills. You can do this with Walmart or Harbor Freight tools. If you have done an oil change you can drain and fill a transmission. While this is specific to the Hybrid, it likely is the same for the EcoBoost (and JK jeeps for what it's worth just different sockets and fluid).

You are responsible for your actions and assume all risk.

Tools

• 3/8 ratchet
• 3/8 extension - 5 inches
• 14 mm socket - Transmission drain bolt
• 10 mm hex socket - Transmission fill
• 21 mm socket - lug nuts (or use the one that came with truck)
• 4 mm hex socket - under engine splash guard
• Flashlight
• Funnel
• Mop bucket or oil receptacle
• Safety glasses
• Mechanix gloves
• Truck Jack
• Jack Stand
• Tire chock

Supplies

• Paper towels
• Nitrile gloves
• degreaser
• 6 quarts of Motorcraft Mercon ULV (toxic)
  • I always get extra if I spill

Step By Step
Lifting the truck

1. Activate the parking brake
2. Loosen but do not remove the lug nuts (21 mm socket)of the front driver tire
3. Chock the rear tires
4. Jack the truck up
5. Put the jack stand and lift to appropriate height
6. Remove the tire and side it next to the jack stand
   1. If the jack and stand both fail the tire will function as a stand as a last resort
7. Remove the under engine splash shield

Draining the Transmission

(Note: the blue line is me bolt marking it after I filled it. It is not there from the factory)

1. You will open the fill plug first (picture 1)
   1. This is to ensure that you can fill the transmission. If you cannot remove the fill plug abort and call a mechanic
2. With the 10 mm hex socket remove the transmission fill plug
   1. Mine was pretty tight and I had to use a breaker bar
3. Place the mop bucket or oil receptacle under the oil
4. Remove the Transmission drain bolt using the 14 mm socket (picture 2)
5. Let the transmission oil drain
   1. It is normal for some metal flakes but they should be small

Filling the Transmission

1. Tighten the transmission drain plug. I did 1/4 extra after it got tight
2. Measure the amount of transmission oil that wan removed. This is the same that you will add. I had 4.2 quarts come out and I put 4.5 back
3. Using the funnel begging to fill the transmission through the fill hole
4. Transmission fluid will start to leak as you get near the amount you removed
5. When full, tighten the transmission fill bolt. I did 1/4 extra turn after it got tight.
6. Congrats you did a transmission drain and fill!

Finishing

1. Replace the tire
2. Finger tighten the lug nuts
3. Make sure there is nothing under the truck
4. Jack the truck up some to remove the jack stand
5. Slowly lower the truck
6. Tighten the lug nuts
7. Turn the truck on
8. Cycle from parking>reverse>neutral>drive 4-5 times
9. Road test the truck by driving it to a local car part store to recycle the transmission fluid
10. Enjoy a cold beverage when you get home

good idea marking the plug as a reference

Thank you for this write up. I have been waiting for a video of being it done, but that life.
Just a bit in the dark.

Go to second picture and drain the fluid, count the amount so to put the same back.

Open the plug in in top picture after inserting a pump into the hole and begin
pumping fluid until the fluid amount taken out of tranny begins to drippled out of the top picture.


I probably misinterpretated your steps.

Nice write up, I just completed the service.

Thanks for this write up. was there a filter? rock auto shows a filter for these.
