FordTechMakuloco This doesn't tie in directly with this topic but was wondering how reliable is the na 3.5 duratec you get with vehicles like the base explorer?

[@KB-bh9hp]

Stinky Cheese I presume you're talking to me?Yeah heard they also beefed up the 6 speed auto for the 2016 refresh so that should be far more reliable as well.

[@F-XLT]

A little off subject but why is my NP205 Transfer case (running 80-90 weight gear oil) so very hot to touch after just driving around in 2 hi. Its in my 1976 f-150 XLT with a 300ci straight six, standard 4 speed transmission, 4x4.

[@BustinCasts]

@FordTechMakuloco I tried running a Google search on LV in transfer cases and can't find any info on the Ford approval. Is this something that happened recently? I trust you 110%, it's just kind of odd to me that there isn't more information out there about it. Appreciate all you do and keep the videos coming brother.

[@BustinCasts]

Ended up finally finding some info. Of course you were spot on my man. Thanks for all you do for the Ford community.

[@tbmproductionsdj1]

Brian I want to thank you for all the work you did on my F350. All the fluids in my truck were from the factory and the dealership told me they did not need to change out all of these fluids. After watching your videos and also talking to you I will bring this truck back to you for anything that is not covered by warranty for repairs. Again thank you and your family for being so awesome I look forward to see more your videos. If anyone is in the Chicagoland area and has a Ford this is the man you need to see for any repair.

[@edvinkler8434]

Great tips, I would add one thing. When complete and after road test/leakage check I would put a dab of grease inside the hex wrench well. The next time you change fluid there would not be buildup in well and if there is some debris it will come out easier. Great job though.

[@etripp111]

I realize this is a 2 year old video so just to let you know, went to Ford dealer to get transfer case fluid and no longer available. They are now recommending the Mercon LV tranny fluid for the transfer case. At least for my 2012 f150. Thanks for the videos, they are fantastic.

[@MrJoedotmac]

Same experience here with an additional note. There's a white sticker on my 2013 F150 transfer case above to the drain plug that states "fill with Mercon LV only".

[@wilmontparker2184]

Thanks for the clarification!!!

[@vitopannucci2001]

Important for 2011-2014 F150 (always double check) - If you have the 4A option (Lariat and higher) on your 4x4 knob, you use the Mercon. If you don't have it (2H 4H 4L) (XLT or lower), you use the XL-12.

[@pierreverdoni]

@@vitopannucci2001 you mean mercon LV ? with the 4a option

[@vitopannucci2001]

@@pierreverdoni Yes, it should be on page 401 of the manual. As long as it's a 2012-2014 then I believe so, the 4A one is Torque on Demand, takes 1.5 quarts of Mercon LV not the XL-12

[@geoffrobert8818]

I watched you ur video last night and changed the transfer case oil in my 2014 F150 without a problem. Your videos are very good!!!! Thanks so much.

[@toddjamison77]

Did you use a torque wrench? I've been looking everywhere and I can't for the life of me find what the torque spec is for the transfer case in the 2014.

[@heavysnow8616]

It’s stamped on the T-case

[@JerryPonds]

​@toddjamison77 just get it snug, and then ⅛ turn. Usually works for me

[@MichaelLangton-l7u]

I have same vehicle what kind of sealant do you put on plugs before tightening

[@DesertRatGardener]

Today at the Ford dealership parts dept, they gave me Mercon V bottles for my transfer case fluid. Thanks to you, I refused them, explaining I saw a Ford mechanic on You Tube advise against it. Parts guy did not know. But again thanks to you, he found the right fluid. Really appreciate you doing these helpful videos.

[@wildbill23c]

LOL Mercon V will work just fine in a transfer case. Mercon V supercedes the Mercon 4 and 3. You just can't mix Mercon V with other fluids...so if you drain a transfer case that had Mercon 3 for example you can fill it back up with Mercon V. Mercon V is synthetic, Mercon 4 and lower are conventional ATF. Mercon LV is low viscosity fluid used in a lot of the newer transmissions and PTU's.

[@twobeer3316]

@@wildbill23c Yeah, I can't imagine Mercon V would damage a simple chain drive transfer case.

[@danielloerzel5917]

I just did this last week after watching other videos on the procedure. They didn’t mention needfor thread sealer or that torque could crack case. Luckily I used a small ratchet and took it easy. No thread sealer but no leaks so far.

[@romansroad2007]

Daniel Loerzel I think it’s fine or The white Teflon tape. Just to seal it better

[@NORTHSHOREEDITS]

The flexible hose from a DEF container works perfectly to use as a fill tube

[@alexpope5327]

Man your channel is a life saver. My F-150 just turned 70K so I know what I will be doing next weekend. Both axles and T-case I can do myself, the Trans I might have to get done professionally but at least I can do this much...

[@myriadcorp]

I just changed my Expedition 4x4 transfer case last week. It needs 2 quarts but I couldn't get all 2 quarts in. There was 4oz left in the bottle. The ground was not perfectly level. It was the best I could do. All I could find to put in was Mobile 1 ATF. So far nothing is leaking so I called it good.

[@FordTechMakuloco]

Yeah they don't take much at all very cheap maintenance.

[@JoeyHtz]

Another great video and appreciate the upload Brian! I did my front diff & transfer case fluids today.... BUT 5 quarts came out of my T-Case😵. I bought my 02' f250 4x4 5.4l in late 04' with 46k. I then had all the fluids changed for piece of mind shortly after. It didn't even take 2 qts b4 it started flowing out the fill hole. I'm writing this hesitantly because I'm in disbelief about it and I watched as my oil pan quickly filled past the 5-quart mark

[@sergiojacquez2277]

Great video but when draining you should always pump in a little new fluid to push out old fluid so you can have a clean case than pump rest of new fluid in till it's full.

[@jorgefonseca9225]

Great vedeo and great explanation 👍 I have a excursión 7.3 and I used a ATF dexron 4 fluid 😊 and every 50.000kms! I changed and still working like new 👌👍 cheers from Norway

[@The_Bearded_Biker]

I got tired of the humming while in 4x4 so I drained out my tcase and refilled with 75w90 gear oil, works great and no more humming.

[@ToxicMisfitsYt]

You can also take the top off a gear oil container and put on the transfer fluid and squeeze it in there

[@Kyle-Veilleux]

my general rule when tightening drain plugs is to lightly snug em up and check for leaks.. cause in my option id rather have it weep out a bit and then snug it up a bit more rather than splitting the case as he mentions in the video.. ive split a casing before and it doesn't take much. ...

[@hawaiianf1504]

Another Great Video! Thanks Bruddah! I have three of those quart pumps. One each for Trans oil fill, regular oil fill and lastly one for my hand cleaner. Bruddah, here is a Tips & Tricks idea for you. I've found from many years of working with pipes and fittings and such that it is easy to overtighten NPT threads to the point that they will cut new threads into the metal, especially soft metal like aluminum that they are screwed in to. Reason being is most all pipe threads under 2 inch are tapered and after repeated tightening, especially over tightening, the plugs will actually start cutting new threads (steel plug vs aluminum housings) into what you're putting the fitting in and also over time wear down the threads on the fittings you're installing. This is why you'll notice that the plug went in a little more then when you removed the plug. Best to replace the pipe plug when the top of the plug goes into the housing or before. In the past I've had to make a larger plug hole and use a larger plug. I would suggest making an adapter with an o-ring seal and straight machine threads that screws into an adapter with pipe threads on one end and straight machine threads on the other end. The adapter fitting cost less than $10 and it extends the plug drain hole out a little more to clear the housing, The old oil now drains right into the bucket without getting oil all over the housings, frame, your floor and what not. Bottom line - no more mess and you have a solid seal for years. I've done this many times and for $.15 cents I change out the plug's O-Ring maybe every five years or whenever it needs it.

[@FordTechMakuloco]

Very good info I am always weary of cracking the housing when using pipe plugs anywhere whether it is automotive or construction work.

[@hawaiianf1504]

liquid teflon is the best lubricating sealant that I know of. It should always be put on so it isn't on the first and last two threads of the plug. This so it won't drip or fall into the housing and mix with the fluids. When the fitting top is close to the housing when tightened it's past time to replace. Usually on pipe threaded fittings I only put it on the middle of the cleaned threads. New NPT fittings seal at 3/4" of it's length. Any more than that i'd be looking for a new plug or a new idea.

[@sanity1977]

Great tip on the hand position on the ratchet if you don't use a torque wrench! Great video as always...

[@hameed5234]

133 lb-in for the f150s drain and fill plug also the service manual says you should fill till 10mm below the top fill plug...1.4qt total.

[@infotechsailor]

LMAO! thank you.. i know he says 'torque spec is critical!' then doesnt give torque spec.... :/

[@rayh91]

On every car I do. I like to loosen the fill plug to the last one or two threads. Remove the drain plug and then remove the fill right after so it's easier to "catch" the fluid coming out.

[@FordTechMakuloco]

I like to remove the fill plug completely first to see the exact level that has been inside this whole time as shown here the level was perfect this tells me allot like the fact it was filled correctly, it has not lost any fluid and it is not gaining fluid from a cross leak between the transmission and transfer case so just by pulling the fill plug first you can get a ton of information.

[@rayh91]

Very good point! I work on Acuras and we don't have that issue but I will get in the habit of doing the fill plug first.

[@STREETSTANG07]

Thank you for the reply. And yes it is a standard 14mmx1.25 thread but the hole has a shoulder first then the threads that makes the short threads on the compression fitting useless. Thanks anyway.

[@romansroad2007]

John Lacaria maybe your transmission is leaking in to the transfer case he said

[@dnlmachine4287]

Great vids my man, you are the go to Ford tech for me on youtube. Save a few gear fluid bottle lids, the pointy ones. Cut them at different distances for varying hole sizes. Use them on top of your 1 liter fluid bottles as a filler tip. Can put clear nylon tube on them as well. Squeezable for forcing fluids upwards too. The uncut lid and their little covering tips make good hose and line plugs/caps as well. Stay gold.

[@sdsuch4353]

I do all that, too. Just saying, do like dnl

[@theobserver3021]

I gotta tell ya I did the transfer case fluid change on my 2016 with 28000 miles which about half is towing our 7000lb camper. This is the 1st time I have ever done this procedure. You had me concerned. The fluid that came out looked new me. Pretty much same color as what I put in. Took less than 2 quarts. I won't change that out again until another 50000 miles. Now I'm wondering if I need to change the fluid in the rear diff this soon.

[@pm_7266]

Thanks so much @FordTechMakuloco, great videos and advise! Question regarding the correct transfer case fluid to use on a 2011 F150 ecoboost: I went to one of my local Ford dealers to get the XL12 for my transfer case and they said that back on 2022 Ford discontinued the XL12 and only the Mercon LV is available now. I am confused because my owners manual indicates to use XL12 and if I got it right you in your video say no to use Mercon . What should I do? Thanks, confused Canuck

[@f1620mm]

Mercon LV is the same as what my 2009 Ford Expedition -80 Transmission takes also! Sweet!

[@wildbill23c]

Mercon LV is different than Mercon V. Mercon LV is low viscosity ATF, Mercon V is just synthetic ATV which supercedes Mercon IV, and Mercon III.

Would it be a good idea to pump new fluid in top until clean fluid came out drain before plugging? Seems like it would be more effective.

[@rwmcmullin]

For you first timers doing this project, please note this video demonstrated some "best practices" that should become habit when doing fluid changes on a vehicle's driveline: 1. Always remove the fill plug first! You don't want to remove the drain plug and drain the transfer case only to discover you can't remove the fill plug. 2. Use a thread sealant (the plug will require less torque to seal properly). 3. Choke up on the ratchet handle to avoid over tightening (trust the sealant). 4. Use brake cleaner to tidy up. Why? Because if you leave the area clean, it's easier to find leaks later...

[@LMacNeill]

I assume this would be pretty much the same thing on a 2019 4x4 Ford Ranger, yes? I mean, the Ranger is 2 years newer than this video, but how much could they have changed, really? Does anyone know for sure?

[@Justicejamesb]

Your videos are awesome, thanks so much for them!!

[@rickketchumn4458]

Do you have a video on how change the rear transfer case seal out put shaft on 2016 f 250 thanks

[@tedthornton7791]

That top plug. You said barely seeping out. Does it need to be operating temperature. Thanks

[@ryankristybowers1843]

Love your channel! You’ve help me out tremendously. Thank you! I have a 2001 Ranger 4x4. My transfer case has what looks like a counter weight or something on the left side. Is the drain plug behind that?? I only can seen one plug that is in the middle of the case.

[@carthrasher8022]

Thanks Brian for your efforts to share your knowledge.

[@galehess6676]

For a little flush, leave the lower open and put in a pint of fresh fluid in the top and let it run out again. Or fill/drive and drain if you want overkill.

[@kevinbutler5491]

Thanks to your wonderful video I just did mine. However it took almost 2 1/2 quarts before I started to get any outflow from the fill hole. I also appreciate your advice regarding how to tighten those bolts without a torque wrench.

[@Alan_Edwards]

What model truck do you have that took 2-1/2 quarts? I have a 2010 F150 and need to do a change. Wondering if 2-1/2 is normal? Stuff is not cheap.

[@kevinbutler5491]

Alan, sorry it’s taken me so long to reply. I have a 2013 F350 . I kept adding until a little bit dribbled out indicating the fluid level had reached the opening. I cleaned up my mess and put the fill bolt back in. When I looked it was approximately 2 1/2 quarts.

[@Alan_Edwards]

@@kevinbutler5491 Good to know. I am doing mine and bought 3 Qts to be safe and the stuff is not cheap. I ended up getting it on eBay. Was cheaper than Amazon and the bottle looked the same as what he uses in the video.

[@jaimesoto5836]

Excellent video. Wonder to know what motorcraft fluid do I need for a 4R100 trans ? Thanks in advance.

[@FordTechMakuloco]

Mercon V for the transmission itself- amzn.to/2nFE4LZ

[@jaimesoto5836]

Excellent.. Thank you.

[@swheeler6848]

OCD may be kicking in, but I typically push a pint of new fluid into the fill hole, after drainage, thinking I’m pushing out older fluid and grime out.

[@FordTechMakuloco]

We do that sometimes when it’s dark enough

[@angileques]

Hi Brian. Thank you for another awesome video!!! Would this be the same procedure for my 2005 Escape XLT 4x4? My dad thinks the transfer case is leaking fluid too...

[@FordTechMakuloco]

No yours is a PTU and uses 75w-140 but should be changed every 30k still- amzn.to/2nFBKGM

[@robertvidmosko]

Is the procedure the same for a 1995 f150 ? I'm getting ready to do the transfer case and the differentials. She has 260k miles. I recently bought it.

[@jamesweir139]

I love spraying sh down with brake clean when I'm done 👌

[@Pirateflixs]

I like your videos, I have a question how I can remove the cover back transmission of 2006 ford escape 4 cylinders ? can you make a video to show how to open it without damaging the transmission pump? thanks

[@FordTechMakuloco]

On the cd4e you never want to do this in car most times the trans explodes after.

[@Pirateflixs]

FordTechMakuloco Then how do I fix it if the lid is damaged and the liquid came out of there?

[@CubasAutomotive]

thumps up you pull the entire trans & work on it then

[@goldmember320]

kick ass vids dood! So, trans fluid/filt every 15k, differential fluid every 30k, transfer case every 30k. I'm wondering; should loaded service body trucks and trucks that do frequent trailor hauling change those drivetrain fluids in more frequent intervals (like every 10k instead of 15k)?
