I'm posting this in the maintenance section rather than the transmission section because it's the servicing instructions for the transmission on the EcoBoosts. The revision of the service manual is 2021 so unless something drastic changes, it should remain current for a while for the 8F35's. If something does change and someone informs me of it, I will update the post accordingly.

I'll start with the how to fluid level check procedure:

Ford Maverick Transmission fluid check and service, with torque specs (per the Service Manual) check 004.PNG


Ford Maverick Transmission fluid check and service, with torque specs (per the Service Manual) Swap 001.PNG


The rest of the procedure for the fluid exchange is the same as the fluid level check.

Now the drain and refill procedure:

Pretty simple procedure. I'm sure you can skip the step that calls for using something like Torque to monitor the TFT PID (temperature), but it does need to remain at operating temperature during the procedure.

Hope this helps.

Ford also states that a "swap" is okay, likely because there does not seem to be a filter:

Pretty simple procedure. I'm sure you can skip the step that calls for using something like Torque to monitor the TFT PID (temperature), but it does need to remain at operating temperature during the procedure or you can drive it a bit with the air cleaner off before you continue to get it to operating temp then recheck the fluid level. That would be my recommendation at least. If you have a good enough lift, put it in drive and let the wheels spin while you cycle gears to get the fluid circulation at least.

Hope this helps.
Thanks for posting this. It confirms that it's as simple as an oil change.

The only thing I would do different for a drain + fill is open the fill first. That way you know that you can fill it up. If you drain it and you cannot open the fill, it's not going to be fun

Do you have access to more from the maintenance manual? About the only thing I cannot figure out is how to flush the coolant for HVB. My gut feeling is that it will be vacuum method to get all the air out

You can also look up Ford Tech Makuloco's Youtube video for the drain/fill procedure for the 2013-2019 6F35 transmission. It's fairly comprehensive and pretty much the same as the 8F35 found in the Maverick.

Nice to see the actual Service Manual procedure with torque specs and everything all in one place. This should be a sticky.
Yea it's a little interesting the only stickies in this section are pretty much garbage and stuff you can find in the owners manual with tons of terrible "information" to boot. I've made a couple threads so far like this and no doubt they will get buried because majority of people won't even change their own brakes or fluids.

Thanks for the info! It must be too expensive for Ford to install a dipstick. So we "dipsticks" can check it the "old fashioned" way! 😵

Love this! I have found that respecting most factory transmission fluid change intervals results in early death of transmissions. The only exception I've found is Honda's 30k mile drain and fill procedure. I've actually pulled a tranny back from what seemed to be it's demise by bumping transmission fluid change intervals up.

Anyone else find the 150k mile recommended change interval in the owners manual to be complete negligence on part of ford?

If you read it fully, if you do the mulltipoint inspection at each oil change that is what actually dictates when the fluid should get changed. Unless you took an extended warranty that change is outside the limit. Here is the rub concerning warranties, depending the dealer or Ford if you do the multipoint inspection and the tranny goes how do you prove you checked the fluid first. So with that said if you want warranty coverage you really need to have the dealer do it so it is on record. Now if the dealer didn't check the tranny fluid on the inspection like the one I go to unless you ask them to do it, it is on them not you if anything breaks. Usually what the dealers will do to honor the warranty is get you on a transmission fluid flush before they will replace the transmission under warranty.

Ick, wouldn't the tranny flush be part of the warranty service?

Also, forgive me for not reading the manual fully, I haven't taken delivery yet. I thought there is no dipstick, how do we check fluid for multipoint, the overflow port?

You still have to pay to have it flushed in either case unless you paid for an extended maintanence plan which covers fluids. The only way to rule out bad fluid as the source of the problem is to change the fluid first and that is how they get around $200 or so out of you to replace a transmission under warranty.

Take off the transmission vent cap and use a $9 siphon pump to pull out some fluid. If you can't get any from there then get it from the fluid leveling plug opening. Color and smell will tell the tale for the fluid.

It's very easy to access the fluid level plug on the side of the transmission. You can get to it by simply turning the drivers side wheel outwards and using an extension to reach it.

Also a good idea to invest in a spring clamp plier that locks to make removing and replacing that vent cap easier.

Just food for thought before you tackle this job.

I've never seen fluid replacements be part of any warranty either, and most shops will quote the basic service intervals that are the longest for their maintenance plans. After what I saw in the RDU and PTU, I'm not going to risk a flush recycling any metal particles through the valve body in the opposite direction of their normal flow. I also don't know whether they use plastic or metal balls in there, but I know for a previous F150 I had they were plastic and would degrade over time, which allowed much more stuff including plastic particles that may have chipped from the valve body linings to lodge in more spots as well. Drain and refill should be plenty somewhere in the 30-60k interval. Just my two cents, as with any fluid, sooner/more often is better.

Figured this is the right thread to get some clarity....

I recently had the hybrid(hybrids in general) talked up to me. It made me faulter a tad in my Ecoboost choice, but then reality set in and I realized it would take me 3 years to break even on gas savings for the $1500 hybrid upcharge.

I was read a Landry list of maintenance and repairs the Ecoboost would require to hit 200k and the hybrid wouldn't. Alternator, starter, tranny rebuild, turbo replacement, etc.

Was I just victim of a hybrid enthusiast over justifying their own purchase or do those of you who have experience with the Ecoboost see some validity in it needing a lot of work over the long run?

To me, most of my experience the past 20 years with my 2 Honda's, it doesn't seem that hard to get a modern ICE to 200k. Keep up with good fluid maintenance, spark plugs, water pump and belts at 100k, but otherwise easy breezy. As long as you don't beat the crap out of it.
