Sounds simple. Not with this car.

The SA at my dealer, who is very cool, says not to do it.

No E9X sold at this dealership since 2005 has had this service!

Even if a car had tranny repair done, the fluid was drained and saved and put back in, I am told.

He says the fresh fluid will break loose deposits inside the transmission and cause issues. This has happened to E9X cars who have had this service done.
The new fluid with it's strong detergents are the cause.

At 49000mi I would like to have this done but am worried. My CPO warranty expires in October.

Please chime in your thoughts and experiences. Thanks.

Yes. No problems and no regrets. (Didn't change filter, yet.) http://www.e90post.com/forums/showth...y+transmission

Cars like fresh fluid.

If they never do it, HTF would he know what might happen? I'd find another dealer. YES, change the fluid and the filter, especially if you are going to keep the car a long time. You are at the right mileage to do it.

If they are really putting dirty fluid back into repaired transmissions, they should be shot!

There is NO SUCH THING AS LIFETIME FLUIDS in cars. Lifetime of the warranty, more like!

+1 I think I read somewhere that if they service the transmission for whatever reason they are NOT suppose to reuse the fluid.

I am sure he has access to data from all dealerships.

I know that the transmission oil pan is integrated with the filter.

So the pan must be changed out for a new filter. How about flushing it out?
Has anybody done this before the new fluid is added?

Last month I changed fluids in the gearbox, both differentials, transfer case, and coolant. I am not going to trust their "lifetime fluids" concept, because to them, lifetime is the warranty period.

BMW's reputation will be basically zero in another 3-4 years then, if their short-sighted "lifetime fluids" business starts wrecking car after car.

This will be subject to HUGE news and government scrutiny.

Wow, talking about conspiracy theories. While I agree that there should be a fluid replacement schedule I doubt that your predictions will come true. There are cars with nearly 200,000 miles on them that are doing just fine following the lifetime fluid theory.

i used to change my atf in my e46 and it made a huge difference in shifting and smoothness of power delivery. I have not done it yet on my e90 but i am about to i used OEM filter and amsoil universal ATF

Nah, most people will sell their car before 100,000 miles so the new owner will blame the old owner for beating on it or whatever.

That was the point I was making. Either BMW's reputation will go in the toilet or they know something.

And BMW resale value will go in the toilet because all the companies that keep track of the statistics will show how crappy used BMWs are for reliability. People do follow these sites and companies, you know.

Like Jaguar in the 90s.

I kid you not: I saw quite a few 3-4 year old (at the time) V12 top-end Jaguars selling for 1/4th original sticker. Why? Because no one in their right minds would buy one of these just-look-at-it-wrong-and-it-dies monstrosities.

Or pretty much every GM car also made in the 80s and 90s.

[galahad05]

Having said all that, I'm definitely changing my fluids.

BMW may know some stuff we don't about automobile reliability/oil/fluid quality, etc., but I'm thinking they made a mistake here. We'll see in 3-4 years.

I helped my buddy changed out his 325xi at 100K. He saved app $200 bucks, we broke two screws due to the torque wrench for the low spec that we did not have. Anyway, we were ending up of using standard one and his car runs without any problem til today. I will have the stearship do it when it up to 100K if I still own it. My 0.02 cents.

[David9962000]

If you plan on keeping it for a long time, change it.

[Chriztofor]

As a sidenote, the pan may state lifetime, but Bmw's warranty and service booklet states 100,000 miles.

This looks intersting : trans oil analysis on lifetime fill http://forums.bimmerforums.com/forum....php?t=1372101

Take a guess what the results say.....

And another trans oil analysis. http://www.e90post.com/forums/showthread.php?t=499686

[bumere90]

Reuse the old fluid ? What a bs..Then why do they sell trans fluid then?
I am at 97k I replaced the trans fluid and it was looking the same as the new fluid. I wouldn't bother replacing it so early 50k is reallly nothing.

[FVM3]

change it and go to another dealer. My dealer recommends me to change engine oil every 15k miles, that doesnt make sense to me

[galahad05]

I completely agree with the "change all 'lifetime' fluids at 100k" approach. A bit earlier if you're really worried.

I figure that by 100k miles, I'll have been saving car payments for so long that the cost of a complete fluid switch would be a drop in the bucket.

[JC316]

I'd have it changed. I'm paranoid like that.
