Ford Super Duty Transfer Case Fluid - F-250 F-350

[@coreycoggins8840]

“So be careful there..” classic quote.

[@RetirednbrokeinPa]

I’d say the last fluid change was pencil whipped. I changed mine at 52,000 and it was not terribly dark.

[@treasurestatetoolbags]

Yeah, I'm afraid that was the probably case on mine. Fortunately no issues still - fingers crossed, lol.

[@stevem6711]

Having a dealer change fluids before a used purchase really is no guarantee they actually did it. They will, and do lie about it.

[@Hardstyler981]

Had a dealer not even let me drive b4 buying

[@justindailey4265]

Beautiful ridgeback!

[@larryyang976]

Thanks for the video! I did a quick search on Google and their AI says the fill/drain plug torque is 24fl/lb, which sounds about right.

[@treasurestatetoolbags]

Good old AI. Yeah, not sure on what the spec is - I should probably get the service manual for my truck, lol.

[@Robzombie847]

Helpful video. Just a lil tip. That helped me. The skid plate. I just unbolted the 2 screws by the drain plug. And let it hang on An angle. And let gravity do the rest

[@FloridaMadeMike]

Great Video and forewarning and explanation all around! Keep making more videos

[@ttnt3332]

Very possible that they used the wrong fluid before, or didn't even change it. Yet if they used synthetic even at 93k it would not be black like that

[@treasurestatetoolbags]

Yeah, I was confused when I saw that, I thought the same thing. Seems to still be working fine though.

[@nick7.3]

Did you ever end up changing that output seal? I can see mine flings a small amount of oil up underneath my cab front that spot

[@treasurestatetoolbags]

Not yet, still no leaks on mine.

[@jasonkubitz9410]

Yikes, I'm at 78K and haven't done mine yet. Going to do it next weekend now lol.

[@treasurestatetoolbags]

Yep, it'll sneak up on you.

[@jasonkubitz9410]

@@treasurestatetoolbags I'll probably just take my skid plate off since the dealer forgot two screws in it when they did my upper oil pan 🤦 This is the reason for me doing this stuff myself. I don't trust anyone these days.

[@jasonkubitz9410]

​@@treasurestatetoolbagsWeird, I just checked my manual and it tells me 150K for the transfer case for the diesel maintenance. Same for the trans. I'm doing both. I'm not chancing it.

[@treasurestatetoolbags]

Interesting... fordtechmakuloco did a really good video on "lifetime fluids" or high mileage interval fluids. Definitely worth the watch and some really good points made. For how easy the t-case is and being only 2 quarts, I'm going to change it quite a bit more frequently than even the 60k - maybe even yearly going into summer - maybe not that much, lol. I did do my transmission too, a drop and fill with a new filter, just haven't gotten around to editing the video yet - again, just 7 or so quarts of fluid to do a partial refresh of the trans fluid additive package - feels like cheap insurance.

[@jasonkubitz9410]

@@treasurestatetoolbags Ya, I've been following that guy when he started. Along with Arod. I have never followed the manufacturer recommended maintenance intervals. I've already done both diffs and about to do them again. Is it overkill? 🤷🏻‍♂️ Gives me a piece of mind though. I just totally slipped on my transfer case maintenance. That being said, I have a buddy with a 2016 diesel and he goes by the manufacturer intervals. He has well over 300K on his truck with zero issues. He tows a dump trailer daily for his business too.

[@outdoorcooks488]

Does the transfer case only activate in 4wd?

[@treasurestatetoolbags]

The front output engages when in 4WD. The rear output is always spinning - so there is always fluid moving around the t-case. The chain that couples the front and rear output engages in 4WD, really starting to move the fluid around and creating more friction.

[@MrMadaket78]

Well done, thank you

[@charlesyoungblood7561]

Take a piece of chloroplast bend it to make a funnel over the plate . Works for me like a charm and no removing the brace. Oh! Great job.

[@treasurestatetoolbags]

Nice, yeah, next time I'll be using some plastic or an aluminum pan, was a bit messy. Thanks for watching!

[@FordManiac76]

I just use some cardboard

[@genntown8717]

Mine is at almost 50k miles 2017 6.7. I might just do it before 60

[@treasurestatetoolbags]

Yeah, wouldn't hurt. I'm planning on doing mine every 30k from now on - paying for 2 quarts of fluid is cheap insurance.
