Hi,

I looked thru the schedule maintenance manual and didn't see when to replace the transmission oil for "schedule 1" or "schedule 2".
Can someone help me?
Here's a link to the schedule.:
Infiniti G37 suggested maintenance and inspection schedules

I notice for the "premium schedule" it's 30k. But for the schedule 1 or 2 it's only dotted to inspect the fluid.

Here's some pics of the g-ride!
Help? Thanks

 

I changed mine at 60K. Probably do it again at 90K. Also, did the diff at the same time.

 

Glenn2008, but if we're not going with the premium schedule does that mean our tranny fluid never needs to be changed?

 

Personally, schedule or no schedule, I wouldn't go more than 60k miles. Oil does break down and it's a simple thing to do.

 

the OP raises a good question. there are several preventative maintenance items that have ambiguous service intervals, in particular if one does not follow the "premium schedule". which is a lot of us since the "schedule 1" service schedule is more than adequate for a routine daily driver like the G37.

brake fluid, diff fluid, clutch fluid, gearbox fluid, power steering fluid and likely another item or two all need to be changed over time or mileage, but the OM is vague on when. the rule of thumb most guys on here use is 3yrs/30-36k miles. except for pwr steering which could likely be stretched out to 4yrs/48k miles+.

also, it is wise to do the drive belt at about the 5yr/60k mark.
