Good morning all.

I am planning to change out my transfer case fluid on my 2012 G37xS Coupe.

I searched in the DIY for pictures on how a transfer case looks like and where it is located. I only found pictures for a sedan.

I looked under my car and found what I think is the transfer case fill bolt and drain plug on the passenger side.

I have attached two pictures of what I saw. Can someone look at my pictures and help me confirmed that I did indeed identify the transfer case, fill bolt and drain plug correctly?

It is the first time I will be doing this job on my own and I want to make sure I don't screw anything up.

Thank you all in advance.

 

You have successfully located the transfer case and identified the drian and fill ports. Be sure to use the correct hex size and get it fully seated so not to strip out the hex inserts (they look a little rusty, thats the only reason I say this). Good luck! Should be quick and easy!

 

Here's a great walkthrough with awesome pictures.

Thank you!

Thank you as well! I actually saw that and pm'ed Buckets about a week ago confirming some steps in the entire process.

I just wanted to confirm that I am looking at the right thing before draining stuff from under the car.



I just want to say you guys are awesome and have helped me a lot!

 

Is filling the front diff & transfer case similar to the rear? Just fill til it over flows, then stops dripping out?

 

From everything that I have found via research and from everyone that I have spoken with, the consensus is "yes".

 

Yep, add until it starts to drip and your done.

 

Actually just to confirm with more people.

Once the fluids are changed, I just re-use the washers right?

I know there is a washer on the rear differential. What about the front differential and the transfer case?

 

Washers are very cheap. Oil and time are not. Might as well change new washers for peace of mind

 

I agree. The thing is, my local Infiniti dealer said they dont carry these washers and they simply reuse them.

 

Ask them for part number and get them yourself. Or place a special order shouldn't take more than a week to get them. I would highly suggest you wait for the washers and do it right the first time.

 

Thanks!

Let me call them again and see if they can provide me with a part number.

The last time I spoke with them, the parts department said "We never sell those washers." and at that point, I requested to be transferred to the service department. At the service department, they patched me to their floor tech and the tech said "we never change them and just re-use them"......

 

jeez. at least my Infiniti Service dept is good, went for oil drain plug washers, they threw me a whole bag for free! paid $10 for 3 for my wife's car.

 

I've done the rear end twice and gear box (6mt) 3 times now. Reused the washers each time without any issues. My last 2 motorcycles used similar aluminum washers for the engine oil drain bolt. Reused it each and every time. Oil changes were done every 3K miles or less. Sold each bike at ~40K miles, never had any leaks.

Now the engine oil drain bolt washer I do replace each time. Why? They're an accordion type design, thin copper. Also, the place I buy oe filters from includes them in the kit.

 

Reuse them man, I always have. Especially if a service tech said they do it, that obviously means they haven't gotten any hateful calls about it later leaking after a service was done.
