Dave, I suggest going to a hardware store and making your way to the plumbing section to get some clear vinyl tubing that is about 5 feet+ long. One inch in thickness might be just enough to get it snug into the fill plug. The idea is you put one end of the vinyl tubing in the fill hole and then on the opposite end attach an appropriate funnel that is raised ABOVE the fill plug, say to your chest as you stand. Pour the differential fluid into the funnel and let gravity do the rest. The vinyl tubing I got was maybe 10 feet, and I had to cut it to size. I used the excess vinyl tubing as a means of getting into the transmission fluid hole as well. This should work for the transfer case as well. BTW, do you check for metal shavings on your fluids? And measure how much came out vs how much was put in last time? And ever used non Honda fluid for transmission, transfer case, and differential according to weights?
Thanks for the helpful video. I went ahead and dropped my spare tire (may as well check the pressure on that while I'm crawling around) and with the spare out of the way, I was able to almost fully sit up under the car which made filling much easier than using a pump. I just got a tube that connects directly to the quart container and was able to hold the bottles higher than the fill hole and just pour the fluid in.
Is it the same from the front process ( transfer case differential) same fluid from dealer ?. It is look like I can’t find the fluid from auto part .thanks.
Nhu Bui the front transfer case for the 2015 MDX with SH-AWD (USA Model) takes Hypoid Gear Oil - HGO-1 - GL-5 from Acura. The oil weight is 75W-85 which there are plenty of similar priced aftermarket brands for but I suggest using Acura fluids for this especially since it’s about the same costs. The Rear Differential for 2015 MDX with SH-AWD (USA Model) takes DPSF Fluid from Acura. Please check with your local Acura dealer for your specific model to make sure 100%.
It's 20mm for the fill and 18mm for the drain, but always check with Acura / Honda for your specific car / model. They will tell you when they call. For me 100% of the time when I go to Acura to buy the fluids they give me the correct washers for free and they give me a 20% discount on the fluids to compete with online pricing.
Robert Law according to the MDX forum they quoted 35 ft/lbs but then someone said that was too tight when they went to loosen it for the next one and then someone suggested 27 ft/lbs. This is why I go with “goodntite” for plugs. I never had a problem but please do what you are comfortable with. One thing you should do is after you fill it don’t tighten it to tight. Drive it around the block and back up and then fill it again until it dribbles out. I have found I can get a few more squirts in when I do that.
To whoever is going to do this, buy a longer and wider vinyl tube plus a funnel via Amazon. Work tube up the wheel well. Then let gravity do the work. Pumping 3.5 quarts takes forever.
Glad you caught that. I don’t have the service manual so I don’t know what the spec is I go by the German spec of goodntite for plugs with a washer. Never had an issue but you should torque it to spec. ;)
How about you not be an ass and just be appreciative that he put together a solid video, saving people hundreds of dollars. Perhaps you could take the time to look up the spec and share it with everyone you pompous douche
Torque specs: 35 ft-lbs or 47 N-m on tightening
Crush washers: 18mm and 20mm
Fluid: DPSF only. There is no substitute.
Information is from the dealer
This was one of the easiest DIY maintenance job thanks to your video. I also removed the spare tire which gave me tons of room to work with.
Peter Phung - I am happy it worked out for you and you saved some cash. It really fairly easy.

Nice! I always love a new tip!
ty very much for taking the video, is this procedure same as 2016 rdx awd?? cause, i cant find the drain or fill holes through the subfram at all???
I have used the mini siphon you stick on a drill and works fast, but if you have a extra set of hands holding the bottle, nice video
RetiredAtenPilot - is that the same as a drill pump? I may try that!
Sorry for being a noob, but how often do you change this fluid and is there a name for the fluid?
Is there a model # for the DPSF fluid? I have a 2016 model.
Thanks
Is it the same from the front process ( transfer case differential) same fluid from dealer ?. It is look like I can’t find the fluid from auto part .thanks.

Ty for the great vids but does that ratchet that you linked have a 3/8 or 1/2 end?
M H 3/8
3/8. But use whatever you have. You can easily use 1/2 too.
Is this the same (Process) for 2018 MDX too?
Should.be. Just confirm with the dealer for your fluid.
One more thing can you give the number of the fluid.
when you say torque it to spec, where can I find the spec ?
Yonghyun Song I use the German spec of “goodntite” I don’t have the service manual but I apply about the same tightness as the oil plug.
Which drain/filler washers did you use?
It's 20mm for the fill and 18mm for the drain, but always check with Acura / Honda for your specific car / model. They will tell you when they call. For me 100% of the time when I go to Acura to buy the fluids they give me the correct washers for free and they give me a 20% discount on the fluids to compete with online pricing.
You should put in the description what the torque spec is for the plug instead of just mention you need to follow the spec…
So what’s the torque spec? Thanks
Robert Law - I don’t have the service manual so I have been using the German spec of goodntite. I apply about the same pressure as the oil plug.
@@DIYDAVE Thanks, I'm about to do the rear differential and transmission fluid on the wife's MDX just wanted to make sure.

@@DIYDAVE Will do, thanks

Steven Ramos - I am always looking for ways to speed up or replace the pumping process. Have you tried this approach. Sounds like a great idea👍🏻
You are making a video on this topic and telling people to torque to spec? Can't you mention the spec? Half as* job.
Glad you caught that. I don’t have the service manual so I don’t know what the spec is I go by the German spec of goodntite for plugs with a washer. Never had an issue but you should torque it to spec. ;)

relax there Jamal, its 34 ft lbs
