Nice! I ended up ordering these pumps from Amazon for just $9: Thanks to RMB5190 for suggesting them!

I personally used Mobile1 75W-90 Synthetic Gear Lube for the differentials. Price was cheap, read great reviews and many people in the trucking forums prefer this to some of the more expensive brand fluids like Redline. The pumps worked PERFECTLY and was a fantastic fit on the Mobile1 containers.

 

bought same style pump at autozone for 6 bucks

 

I had originally bought that one from Autozone too, but then realized the Amazon is 2 for $9. I rather use a different pump for the transfer case since it is tough to fully clean out the fluid.

 

This thread has saved me hundreds by just doing it myself. Thank you too the OP! Front, rear diff and transfer case fluid changed. On a side note, my transfer case fluid looked to have gear oil in it. I've never changed it. I'm hoping it didn't mess anything up too bad. I've changed it over to the correct fluid now so hopefully she's good n happy. 141k miles down still going strong.

 

You think my 2013 G37 Sedan is the same?

 

i can't say with 100% certainty but i don't think Infiniti changed anything in 3 years. Mines a 2010 sedan.

 

hi , but wich year are you been using this gear oil i do have a 2013 g37x and im confused now and i dont have the owner manual . Ahh i do have the x model but weather hot (florida)

 

I also have a 2013 G37X... this is the fluids you need :

Differentials (3qt Mobil 1 75W-90 Gear)
Transfer Case (2 qt Matic-J)

Make sure it is Matic-J! Sometimes cheaper to get from Amazon.

 

thank you sir! .. i heard that the transfer case can use matic-s as the transmission i bought that one since i read that is a substitution for matic j ...what do you think?

 

From what I researched in this thread, at least for our 2013... Matic-S is NOT a proper substitute for Matic-J. You MUST use Matic-J. I am confident about this as I went through a lot of trouble to find Matic-J when I did this job last year on my car as I personally am all for after market fluids but was told to only use J for transfer case. I ended up getting it from my local Infiniti dealer and I asked if they had discounts since it was $$$ and they took off like 30-40%.

 

I used Mobil 1 Full synthetic ATF fluid in the T-case since 30k miles and it was fine until I sold it w/ 100+. Use Nissan fluid for peace of mind if you can but there's alternatives.
