Sounds like it will be more than $50 USD lol

Transmission oil really needs changing?

Ok I just hid 100K Miles a week or so ago, and the car must have noticed, since it needed everything done. I did a cooling overhaul and oil filter gasket replace, but the dealer also recommended changing the trans fluid and diff fluids, like on this forum.

I went underneath to look at the trans case though, and there's a nice sticker under there that says something to the effect of "DO NOT OPEN THIS, DUMMY! Transmission oil shouldn't be changed for life!" So, now I'm quite puzzled. Is this just an American thing? Do I really need to change the oil out?

Bear with me if this is a dumb question, I'm just getting used to the DIY stuff.

BMW says the fluid is "lifetime"] but we all know that's not true

Right, so what's a good recommended interval, 100K? Is it worth going through and truly flushing, or is draining and doing a filter replace enough?

I am sure you will get many different opinions. Personally, I think it depends on your driving environment (city vs highway). More steady state driving, longer distances - change after more miles. I think starting and stopping creates more heat and stress to the fluids.

I changed diffs and transfer case around 70k, trans at 100k. Looked right for me on my X3.

Flushing is the best for the trans. I just did a drain, wipe pan and change filter.

Why use BMW transfer case oil?

Hello all,
I'm new to this site and was reading your responses on the transfer case oil and it's replacement. This is my second BMW my first being a Bavaria, way back in the 80's.
It is however my first X3 and I have it for about a year now. It is a 2004 model and i would like to change all the fluids, at 119K Km, I think it is necessary. Today I saw a youtube video done using a Bently service manual for the X3 and there was another one right after showing the components and a DIY service on a transfer case. The components in there were gears, bearings and a chain with the connecting shafts. i saw nothing that could enforce why you must use BMW type oils. The only requirement which I see would make sense is the 75W type oil which is needed for that type of gears and hardware. Could someone please tell me why one should use these special BMW oils? I know with the transmission it is a different story....DEXTRON 6 and that only, according to the manual.

You are overlooking the clutch packs.

Clutches in there?

I certainly am not aware of the clutches. That is what is under the main cylindrical cup that has the drive shaft passing throught the centre? If there are clutches there as you mentioned then yes, I have no further business questioning BMW and their TF0870 fluid.

Thanks for that response Supercourse!

I have noticed the following when driving at slow speeds and from the dialogues it suggest that the TC may be the problem. Here is my situation, at slow speeds, like in traffic on a hill or on level ground I do hear a "clank" type of sound just before the up shift or downshift. There is a little jerk associated with the sound. I suspect it may be because of the transfer case or the drive shafts may have some play on the joint. The car runs smoothly and accelerates well so I know it may not be a transmission issue. Please advise on what you might suspect it to be.

Yes, there are clutch packs in there. The X drive system uses clutches.

Even without clutch packs, many gear boxes require a "secret sauce" of friction modifiers, including GM and Ford. Modern Ford diesels even require FoMoCo filters to ensure proper starting; aftermarket filters alter oil pressure too much and lead to prolonged starting, believe it or not.

The BMW fluid is pricey, but at least you only need to buy one quart every 30k miles; far cheaper than a single oil change, let alone the 6 performed in the same amount of time.

Thanks Dukedkt 442. Do you feel that the problem i may be having in the other part of my blog is related to the TC?

X-case fluid is definitely over due for fluid change, so start there. If that doesn't solve your problem, check the shaft joints.

If you don't want to buy the OEM stuff. You can buy exactly the same oil from the company directly.

For those wanting to change the oil at the same time.

Ravenol Transfer Fluid TF- 0870

just search google or ebay for it. Much cheaper than the BMW packaged oil.

Check the ravenol website if you need.

While on topic for transfer case fluid, I just finished uploading a new video to showcase how to drain and flush the transfercase (transfer case) for a 2005 E53 X5. At the end, I even show how to use GT1 / DIS to perform the adaptions reset.

As the Land Rover actuator gear has been suggested to replace ours when it fails, because apparently the actuator is the same, I'm wondering if it is just the actuator that is the same or the entire transfer case? The LR fluid capacity seems to be a little higher, but the fluid is only $20/quart from the dealer compared to our $65. Anyone ever look into the LR fluid?

i got a bottle of the Ravenol TF-0870 from Amazon for I think $30 and put it in my transfer case about 5K ago. I wasn't having any problems, no codes, but the original had been in there for 9 years/70K, so it was a preventative measure. So far, no issues at all. Use at your own risk.

I haven't fact checked to see if the Ravenol is the exact same as BMW. For only a 30k difference every year or two (at my fluid change interval), I'm content with the peace of mind.
