ok, that answers my question. The Mazda "gasket" is just an overpriced m18 crush washer. They're cheap at the local auto parts store as that engine oil plug gasket is an overpriced m14 crush washer . Heck, I might even have a few in the basement by accident. Looks like I'm in businessDefinitely not genuine Mazda but I'm okay with that. Not like it's a spark plug! Haha

2013~2016 CX-5 Rear Diff and Transfer Case Fluid Change: Tools, Parts and Links
- Thread starter CX5-SO
- Start date
Yea, nothing special. Hell, I almost never actually change them. But on a trans, diff or xfer case I am a little more picky.
These things are an exact fit FYI. Job took under 45 minutes, eazy peazy. Fluid was a light brownish color. I expected worse since i took it through some overflowing creeks a few times during a flooding rain storm. The top plug was surprisingly dry, drained about 14 ounces.

Is it the first time you change the gear oil on front transfer case and rear differential for your 2016.5 CX-5? How much did you use to fill both? Are you using SG-1?
First time in 7 years and 75k miles of ownership, just the rear differential so far. Plan on transfer case and trans in a few weeks. Took 2/3 quart just like the other folks. Used Mazda G1.

So the factory spec is 0.48 quart and you drained 14 ounces (0.4375 quart) from rear differential. When you refill you needed 0.67 quart to bring the gear oil level to the fill hole brim as stated in the factory workshop manual. The factory fill in rear differential usually is pretty low.

Have not done mine but dont you put it up to the fill hole? That not always the case though. Chevy 1/2 ton trucks always have the pinion seal leaking. Why? Cuz the book says 5/8" to 1-5/8" below the hole is full. And some dummies fill it to the hole. I made that mistake years ago, cought it that same day. Put in 2.75, book says 2.1. Dont be "that guy"

If you read Mazda’s factory workshop manual:
For both front transfer case and rear differential, the manual says fill the gear oil to the brim of the fill hole which is a standard practice to fill the transfer case、differential、and manual transmission. It indeed takes about 0.48 quart like the manual says for front transfer case, but strangely it takes about 0.67 ~ 0.75 quart for real differential although the manual says 0.48 quart!

That's pretty much what I did, just pumped fluid in there and let in run out, put the filler plug back in when it stopped. I was looking at a 2013 service manual (got it on this sight). Some oil was still trapped in the pump and long pump hosing so I can't really tell how much is in there, ended up being 2/3 out of the bottle. What year manual are you quoting from yrwei52?
Some other points as was said before on this thread, it is tight on the top plug. I used my favorite 3/8 drive 12" long ratchet with a pipe attachment for extra torque with a low profile 23mm socket to crack that plug loose, was relatively easy even after being on there for 7 years and subject to the road salt of PENNDOT. Had to get a skinnier 3/8 drive torque wrench to fit in there also, nothing I had fit. Also, that $7 fluid pump from Harbor Freight was fast and efficient. Soaked both plugs with Gibbs lubricant a few days earlier. Can't believe the dealer wanted $200 to do this...un-freaking believable.

The document is for 2016 CX-5 posted by Anchorman a while ago.
Finally found a couple of pdf attachments thanks to our great Anchorman! I converted them to jpg's and here they are:

Just make sure when you follow the procedure, you need 0.75 ~ 0.85 quart gear lube for rear differential than stated 0.48 quart (0.37 quart for gen-2 CX-5).

Thanks for the hint and with 51K miles on my 2016 CX-5 I’m about to do the change too. Can you provide a picture or link on the fluid pump from HFT?
