anyone here check there OWN TRANNY OIL?

Z11 · 09-06-2012, 07:05 PM

dont really want to service my car, dont trust the stupid dealership. but they tell me i cant check the tranny oil, and i cant find the dip stick. and they said they put in the tranny oil from under the vehicle?

Thats correct its a sealed unit and any self maint would require specific tools and procedure that has to followed carefully if not damage could result.

If you need it serviced the dealers about the only ones that can touch it if you're lacking the tools and knowledge.

But to answer your question here I have seen very little people have serviced it on their own. Not that its impossible but just a pia. imo

Automatic tranny should have a dip stick but the manual does not show one.

Service and Maintenance manual says "Automatic transmission fluid for the 370Z is maintenance-free."

Manual Transmission has a drain and a fill plug. Oil level should be up to the fill plug. Differential oil is usually the same.

Supposed to check both after 15k and replace after 30k.

WTF... Check for what? Do you need to remove the oil to check it?

No dipstick on this AT. How many miles on it?

what do they mean by maintenance free? and the other guy said there isnt a dip stick, i know there was for the 350z but i dont see it for the 370z. it has 3000km = 1800 miles

It simply means there is NO service to be done since it's a sealed transmission

Thats the reason there is NO dipstick to check the oil level.

The idea is the fluid is good to about 100k if I remember right. But that doesn't mean it won't need servicing at one time in its life.

1,800 miles don't even think about it anymore. I have the extended warranty so I factored a tranny flush into the price of the warranty.

So what I mean is...

I will drive the car to ~100k miles. If I didn't get the warranty I would have the fluid swapped at 50k miles. The cost (when I called the dealer) was about $250. Since I got the warranty up to 100k miles I won't have it flushed and 'saved' $250 off the price of the warranty (mentally of course

). The manual states that the fluid is lifetime so to remain under warranty I don't have to do anything.

To each his/her own. That's just what I'm doing, not a recommendation.

i guess the same goes for the rear differential fluid, it doesnt need service like the tranny oil? so how doesnt it run out of oil?

nabenson · 09-10-2012, 05:28 PM

Just because it says no maintenance doesn't mean it shouldn't be done. The AT should have a fill and drain like the manual (though the location(s) may be different). For normal every day driving don't worry until 30k miles. Then it should be checked and probably drained and refilled. For hard driving, or track driving you should be doing this closer to 15k miles.

The reality is that it's probably a fluid that gets changes when it smells burned and there's not a set service interval. My Volvo is this way. We have full service for 50k miles and the transmission is not found on the list. I end up paying a different shop to swap it after track events when it's hot because the fluid will end up burned up.

TL;DR - Don't worry until you hit 30/60/90k miles. The dealer WILL change it, but you WILL have to ask them to do it since it's not on their regular schedule.

negative. the rear dif should be changed at about 30k mile intervals. if you abuse or track then do it more often.

No offense...

Didn't you get a manual to read with the car? It's pretty clearly written.

nabenson · 09-11-2012, 05:41 PM

You _could_ use the same oil in the manual transmission and the rear diff, but it's not recommended. They both use a fairly heavy auto gear oil, but in reality you need two different weights. One for the transmission, and one for the rear end. The weights are listed in the owner's manual, and I personally use redline oils in both.

Must have a big reservoir or it's not going to last much more than 100-150k. There must be a way to empty and fill it though. I think it might be time to crawl under the car and start looking.

The MT (manual transmission) and the rear diff both use a "heavy" weight automotive gear oil. In a pinch (worst case!) you could use the same oil in both the transmission and the diff. HOWEVER, you should just use the oil weights as specified in the owner's manual.

I'm using Redline MT-85 in the transmission, and Redline 90w in the diff.
