So I know there's the video for the 2020 escapes for changing the transmission fluid but I wanted to do a video for bronco sports just cuz I found a few little differences.

Just a heads up, I am terrible at making videos and I really don't care that I am.

So for tools you probably want to take off your front driver tire unless you happen to have a lift now. I was able to do mine without putting on ramps or anything but I raised up my air suspension as far as it goes which is I think about equivalent to people with like a 1 or 1/2 in lift.

Now you really don't want to do it on ramps because because the car is supposed to be level and I think that's why I had a little bit of oil come out whenever I took off my leveling plug before I started draining it. I thought that I checked it, but there's a decent chance that it was off by a little bit

Now you need to verify this but mine took motorcraft automatic transmission fluid mercon ULV for ultra low viscosity. It's what most of the Ford transmissions take now. Be it the 8f57, 10r120s or whatever but just double check to make sure.

And again, you can't replace the filter without pulling the whole transmission and splitting the case. So I would recommend doing this every 30,000 miles and I think Ford recommends every 30,000 miles if you are towing or doing anything extreme duty anyways.

Also I put a picture of what my fluid looked like which is at just over 38,000 mi? And it's already got a brown tinge to it. And there was maybe a teeny tiny bit of sparkle. So there's no way this is lifetime fluid. No fluid is lifetime and I would say that this had just gone past the point of starting to be bad. Like I wish I changed it at 30k and I'll definitely be changing it every 30k from now on. But it was still definitely pretty red and clear still also. And I didn't notice any cocaine or metal buildup or anything like that.

Tools:
19mm socket and ratchet
T30 torx
13 mm socket
Flathead screwdriver
Pliers
10 mm hex drive
1 -ft ratchet extension

So the first thing to do is make sure that the car is up to temp and you've been driving around for a while and then I would say once you stop put your hood up to let it cool a little bit for when you get in the engine bay

Next, unless you're on a lift is to put your emergency parking brake on and Chock your rear tires and your front passenger tire

Then you want to take off the front driver side tire And remember to measure before you take it off so you can lower it back down to where it was so the car is level.

Then I would say go ahead and get your skid plate off. And to do this the first thing is to take off the four torx 30 bolts on the front of the plastic bumper that ties to the skid plate. Remember there's only four don't take off the other non-torx bolts on the front bumper you don't need to.


Then loosen the two rear bolts but don't take them all the way off about an eighth of an inch is fine, just a couple of turns That's with the 13 mm socket. Once those are loose end you can use your shoe or some paint cans or something to push up on the skid plate to loosen the bolts to take off the plate and then slide the skid plate out of the way.

Then you want to remove the two plastic screws in my video to undo the snorkel for the air intake.

Then you're going to want to get in the engine bay And first unplug the sensor in the intake tract and pull out the plastic screw and the clip that attaches The wire for that sensor to the lid of the air box. Then use your Flathead to loosen the clamp, holding the intake hose to the air box lid and unclip the air box and then move it out of the way along with the air filter.

Then you're going to gently pull up on the bottom of the air box until it comes out of the three rubber grommets. It takes a little Force but not a lot.

Now You should be able to see the vent tube which has a clamp on it similar to a radiator hose. Take your pliers it may seem like it's tight, but it's pretty easy and squeeze the two ends of the clamp together until they lock in place and then you can just gently pull the clamp off the transmission. There's a little like 1 in tall spout and that's where you're going to fill the transmission with fluid but not yet.

Next take your 10 mm hex drive and your extension and ratchet and you got to kind of slide it around the strut and the CV axle but it's easy to get it in there And just loosen it a couple turns. Don't take it all the way out yet or do just mine leaked a little bit which if it does that means your car is not level enough I assume.

And now you can put your drain pan under your car and take off the drain bolt and wait for the fluid to drain and it's going to take like 10 minutes to really stop dripping.

Now what I like to do before I put the drain bolt back in. It's pour a little fluid down it just to make sure I got the right bolt and also sometimes it can help flush stuff out but I noticed with this one when I poured it in it just came immediately out the bottom and I don't think that really did much.

Then put the drain bolt back in and you can put your funnel on the inlet and start filling it. And as you get past the third bottle I would say slow down, pour some and check the leveling hole but it should take pretty much 5 quarts.

Once it's full and the leveling hole starts leaking, stop wait a few minutes for it to stop leaking. Clean it up And then pour some more just to make sure that it actually got in all the crevices and doesn't want to take a little more fluid and I'll do that like three times assuming you still have more fluid to put in.

And then you can put the leveling bolt back in and put the vent tube back on. And to unclip that clamp just squeeze the ends tight and let go and it'll pop out. It might take a few tries but it'll pop out. You don't have to get in there with a screwdriver or do anything crazy.

At this point, once it's sealed up if you feel comfortable doing so you could start the engine and check for leaks. But honestly it's not that big of a deal. I would just say put everything back together first and then do that. It's too easy to accidentally put it in drive or even just step in the car. Too hard and maybe the Jack moves or who knows what and bad things happen.

When I did mine I got I didn't get to really measure it cuz I spilled some but I would say almost exactly 5 quarts came out of mine.

And if you're like me and you made a mess of oil, what I would say is don't clean it up yet. Put your car back together back it up a couple feet so you're not reaching under your car and then you can easily clean it without your car in the way.

Here's A link to my terrible video. Hopefully this helps.

Just to confirm, you did this transmission fluid change on a ‘23 bronco sport heritage limited with 2.0L engine, 8F35 transmission?

Yes.

I'm pretty sure every broncos sport comes with the same transmission, but double check and then I think it's the same for escapes and Mavericks unless you have the hybrid. But again double check.

So I've been thinking about when I changed my transmission fluid. Why the heck it leaked out of the leveling port when it shouldn't have and I realize what happened. I think I raised my air suspension all the way up and just the way it is. My my front actually goes a little higher than the rear you know normally on a stock one that front's like an inch lower and I just realized that for all you guys who are doing lifts if you are not keeping that stock. Rake you might have the same problem when you go to change your transmission fluid and mine could have been side to side not front to back. I just didn't check. I should have but I would love for someone to change their transmission fluid that did change it to a level front rear versus the stock Ray and see if it affects the leveling hole for how you check your transmission fluid level and you changed the fluid

You also need to make sure the transmission fluid is heated up to the correct operating temperature. 185-200 degrees F.

If you do not, you will overfill the transmission.

Yeah I put that in the prior post in the instructions you want to have it up to temp before you do the oil change. But thanks for adding that. I think that I basically eyeballed it when I put my air suspension out pretty much all the way. And if it's not because I had the front up too far, I probably just didn't have it evened out side to side like I thought. But I'd love to see someone who has like just a leveling kit, change their transmission oil and see if they had leakage from it to see if it does need that rake for it to level correctly.

you NEED to have car running while you add past 3rd bottle or it will just leak out. you need car running in park so that oil fills pump and converter and gives you space to add correct amount THEN it will start to drip from that side hole and you know your are good.. put everything back go for a spin cone back, put in park keep it running remove the side bolt wait got it to drip very little and you are done.

mine at 70k miles

sever stutter gone

will repeat in 300 miles

so much for 150k miles interval.oil was BLACK

quick question, if you measure how much fluid drains out, couldn't you just add the same amount of new fluid without having to go through the whole procedure of letting it warm up and drain out of the leveling plug?

You could, but can you be sure it was filled to the correct level originally? Maybe ... it's a gamble. Cheers!

maybe I missed it but what is the part number for the transmission fluid and how much did you pay for it?

Just a heads up and I'll make a post about it.I was a fuse blue on my air suspension, and I took the opportunity to fix a few other things.And when I went to do the test drive, I noticed that there was some strange sounds when I put it in park.So I did the motor mount test and had someone go through the gears while I watched, and the engine was moving like two inches, which is no bueno.And it turns out that the motor mount was broken.I already took it apart, of course.I have to wait a fucking week for the part to come in.So now I have to bum rides again, but yeah, the motor mount cracked right down the middle, so y'all might want to every now and then.Just open your hoodHave someone go park to reverse to drive?Wait in a few seconds in between and make sure your motor's not shifting more than a few millimeters at the most.And if it is, you've probably got amount out and from what I read online, the lower motor mount on the two point oh's at least is a bitch and a half because you have to drop the whole subframe
