transmission fluid flush question

Do a search and you'll see the dog chasing his tail discussions. No matter what evidence is given on either side people are gonna do what they want. Even more interesting is that people have decided that regardless of what BMW says about servicing their vehicles BMW can't be right or there must be a conspiracy of some sort.

The threads are fun to read though.........http://www.xoutpost.com/bmw-sav-foru...intenance.html

I don't think the OP wanted a debate, I think he just wanted someone to tell him what he should do in his particular circumstances. Which is cool, we all need a little push in the right direction sometimes.

Hopefully he'll do the right thing and leave it alone

Hey no arm wrestle from me. But the question remains. What is the right direction, what is the right thing to do? Who's opinion regarding this issue
is correct? I certainly don't know and that's why I referenced the link to the thread. Now he can make his own decision rather that have others tell him what to do.
After all this decision isn't like what tires should I buy. This decision could cost big time so how much better to let others debate and he can tune in and see the results....

I don't know for definite either, but I know this; if my transmission dies, I would rather be thinking "it was its time to die" as opposed to "did it die because of that flush I did at 110k?". I could live with myself if the former, but would curse myself if the latter.

OK, at the risk of upsetting Dick Thrust and any other extremely well read forum gurus.....


As the owner of a late 2004 X5D that I purchased with 185K on the clock, the transmission when hot lurched quite badly into 1st when pulling up in Drive N mode. So I got the guys at Autologic to drop all the fluids , flush the transmission which can be done with time, and the first thing I noticed is that the lurch was reduced about 50% when hot. That said it has covered another 10K and the lurch is starting to come back and I am getting fed up with shifting into S mode when slowing to a halt (Changes the shift pattern and selects 1st while still rolling up to a halt.) Another fluid change is my next option or some work on the transmission to adjust the 2nd gear band or solenoid operation if possible.

If your transmission is not behaving badly, maybe an oil sample analysis could be performed to see what else is in the oil. Changing the fluid to fresh correct specific synthetic transmission oil would seem like a good idea to me.

Cheers, Dan.

I’m not trying to re-ignite this debate however; if you have a problem with the transmission and are willing to risk the potential outcome when changing fluid then it’s really a no brainer.

I too also have the ‘lurch’ problem although I suspect not as bad as others I’ve read about.
I’ve also learnt to drive around the problem for the most part which involves reducing the brake pedal pressure just as you’re coming to a stop. Prior to owning the X5, I used to brake like this anyway but have learnt to exaggerate this effect a little to combat the problem.
At this stage I’m not willing to risk a transmission rebuild to cure the ‘lurch’ but if the problem gets worse then I may be forced to reconsider.

So has anyone actually done the oil change? and changed the filter?

Ok so I took my X5 to BMW Sydney for a service and inspection 1. My first since buying my new amazing car.
So the final bill was $980!!! But that did include $180 to change brake fluid and labour to do so.
They also gave me a quote for $2100 to change the transmission fluid, transfer case fluid and replace the cam cover gaskets!
Besides the hectic pricing it was certainly interesting to know they suggest to change it.

Had mine flushed & changed last service thankfully it was black & dirty, fixed my shift problems within a week they also did transfer case & diff for $380
I have 2002 E53 4.6is

where did you have this done?

Had it done by Adamstown Car Doctors Newcastle, EXCELLENT for fluids & general maintanance service etc...

BMW wanted $980 for the same job

the flush is just a gravity flush about 4 - 5 times as no one seems to have a power flush adapter large enough for the gearbox...
but it went from black sludge to clean fluid and you can't tell me having dirty old transmission fluid is good...
