I believe it gets checked under the car via the fill plug, meaning there is no dipstick.

 

It is a procedure. No simple means. Dipsticks on auto transmissions have been obsolete for quite some time now. If there are no signs of leakage there is no reason to check it.

Are you having a problem with the transmission that would make you think the level is incorrect?

 

my car is a CPO, I was looking at the service invoice and noticed they changed the driver side axle seal (looked online what that would mean and possible cause of replacement is transmission fluid leak so I was hoping to keep an eye on the level). Any tips to keep an eye on it if it was leaking?

 

I had to top off after adding a transmission cooler to my Q, and there's just no easy way to do so. Like others have said though, unless you see drops (or increase the capacity by adding a cooler), there shouldn't be any real need.

 

If you are one to never look under your car to change oil, rotate tires, etc, and spot a leaking fluid, it would be a good idea to ask to have driveline fluid levels checked by a competent service department when your car is there and up on a lift. If it isn't included in the "complimentary inspection" that is usually provided to sell some supposedly needed service, I would expect to pay an additional 1/2 hour labor charge to have transmission and differential fluid levels checked.

 

In UT, the lowest quote I got to even check the fluid level was $140.

 

Like Rpiotro says it's a procedure, as soon as you remove the filler plug 1 1/2 liters of fluid drains out.

 

Ok I think the proper way would be with engine running, remove filler plug, top up until fluid begins to drain out, replace filler plug. Yamaha filler pumps are on ebay cheap.

 

The transmission temperature needs to be at about 35c or 95F when the fluid starts to drip to check for the correct level.

 

A drain and refill of the 7AT w/VR30 engine is 4 qts (FF to 4:30 of the following video), and a flush is 12 qts:

 

I managed to pull it off with 10 qts. but it was tight. Will do it again soon, switching back to low viscosity fluid.

 

switching back to low viscosity fluid.

So, what did you put into it? And what were you hoping to accomplish?

 

This filler pump on ebay screws in to the drain hole perfectly, no leaks.

Right now I have the very same problem OP had. Maybe someone here knows how to deal with this problem? I bought a new car not so long ago and I don't know how to check transmission oil. Can someone here tell me about it? I've searched in Google, but all I got was ads or damn sophisticated guides. Maybe someone here knows where to find a simple guide?

P.S. Two hours after I wrote this comment, one of my friends sent me this https://transmissioncoolerguide.com/how-to-check-transmission-fluid/ guide. Well, now the problem is solved.

 

See my post #3 in this thread.

 

On the 7AT there are two plugs. One is the main drain plug, and there is another small allen hex drain plug that is the set plug for fluid level. There's an adapter you can get to connect to the main drain plug, and pump in half a qt of fluid into the trans. Get the fluid temp within spec, and pull the level plug, until it comes to a slow drip. That's how you check and set fluid level.

To exchange the trans fluid first get vehicle to temp, drain fluid from main plug, measure what you take out, pump back in the same amount taken out with clean fresh matic S fluid, run vehicle to temp, going through all the gears a few times, then repeat this same process 2 - 3 times. On the final fill up put in a half qt more than what was taken out to set to the correct level using the previously mentioned fluid level check.

 

Back to my previous response. If there are no signs of leakage why would you feel a need to check it? The fluid will not just disappear. Not like the old days where a ruptured vacuum modulator would allow fluid to be sucked into the engine.

 

When buying a used car how are you certain that the fluid is at the correct level? Better safe than sorry, even with no signs of leakage. Its a good, quality habit to know your car in and out and make sure all the fluid levels are at their proper spec. If you had bought the vehicle new, there really is no need to check it, but its still not a terrible idea to know how to if the need ever arises. Sure you could just take it to a dealer for all the maintenance, but some people would rather do the work themselves.

 

my transmission seems to shift funny when i firat take off, like it jumps into second gear or something, or shifts to soon

 

The transmission does do a bit of rev-matching on upshifts in some scenarios such as slight incline/decline
or if there is very light throttle. The programming also tries to put the car into the highest gear possible
for fuel economy sake.

Unless its a really abrupt or rough shift I wouldn't worry too much about it, if it does feel that way
bring it into Infiniti as and have them take a look. Generally speaking these transmissions are rock
solid even when the car is tuned.

 

BuzzLight - Tell your friend that the 90's called to say they took their transmission dipstick back. They grabbed the fanny pack as well if he's looking for it. And while they were at all that they also filed copyright on your username.

 

He was last seen here 11 months ago...I doubt he'll see this.

 

Ah...thanks Pillboy...didn't realize I was in an Easter thread when I responded! Ironic because I like to make snarky comments about going back in a time machine when people respond to an old thread or comment!
