Transmission & differential fluids

Postby MM...Good » Tue Oct 29, 2019 6:58 pm

Hay all -

So I am considering getting the following maintenance done on the M. It's a 2007 with 127K and I don't believe any of this has been done in the past.

Transmission fluid flush and replace
Transfer case drain and replace
Front and Rear differential fluid drain and replace

Has anyone had all of these done and care to share what it cost?

Last time I did those + coolant, it was like $750. My local Nissan dealer would do it for $100 or so less. You're looking at probably $600 for the above from an Infiniti dealer.

I reckon dealers might have different prices based on the state etc. Ilya's prices seem correct - slightly higher than I paid, but you both have AWD and I have RWD.
If you call your local dealer a service rep will quote you their prices on any fluid change. I'm not sure about an actual 'flush' on a gearbox that may still have original fluid. Maybe just a drain / fill might be safer.

I've actually done all 3 on my M. I did a write up on the Front & Rear diff fluid drain/fill and the Transfer Case also. Those would be in the How To Section of this forum. Actually now that I think about I need to update those pics since Photobucket has watermarked them... :facepalm: ... d-faq.html

Actually, it's so easy to do! Do it yourself. 5 quarts of Matic-S ATF are $60 on amazon: ... UTF8&psc=1

Do three drain and refills and that will account for over 3/4ths of the fluid in the tranny. I needed around 8 quarts total.
