For 6MT, how often do I have to change the transmission and diff oil?

 

^ I believe every 30K miles.

 

The "Premium Maintenance Schedule" which IS NOT REQUIRED, calls for every 30K, if you look at schedule 1 and 2, they do not. Regardless, I did do it at 30K and was glad I did. When my 5 - 6 synchro went out at 45K, the very first thing they asked me about it, was did I do the 30K service, and if so, what lube did I use. I was glad to be able to say yes, and I had used GL-4 rated lube, and had receipts to back it up if they wanted to check (they didn't).

 

did both of mine at 35K and will do the next at 70k and 105k

 

Hmmm I was wondering this same thing? I Hardly Drive my G..Mostly on Weekends..it'S an 07..I jus broke 20,000mi...So When Would be a good time for mne to change the Diff and Trans? I only change the Engine Oil..So Wondering when Do I do the rest? LOL I only put on at Most 3-4000mi a Yr! LOL. Do I half to wait to Hit 30K in couple yrs? LOL...

 

Try going to Nissian dealer I believe its "cheaper"

 

You should be just fine waiting until 30K. It's not like it's lubricating the inside of a combustion engine with huge variations in heat, humidity, combustion residue, acids, etc. The tranny and diff are both sealed cases with heavy oil in them. Relatively speaking, it's a pretty easy life for them; 30k is nothing.

 

If your infiniti service advisor likes you he will match nissan's price. They did for me.

 

i did it at 45k and the MT fluid was in a very good shape however the diff was pretty bad which i recommend at 30k for sure!

 

Yep +1 on the 30K but a little over won't kill your car unless you are racing it.

 

I've seen the tranny DIY, but not the diff. Is there one for the diff?

 

Now what kind of fluid do you guys use for the tranny and diff? Just for diy purposes

 

I kinda want to switch my fluids over to Amsoil. But i know Nissans are finicky about their tranny fluids, so i haven't been sure...

 

i did a full swap of all my fluids to amsoil.

 

Did you notice any difference in fluid feel in the gearbox or anything?? Mine gets really notchy in the cold..
