Service bulletin fix for AT owners
 

An answer to those who complained about the automatic transmission holding gears too long on uphills. Just passing this on if someone hasn't already read it elsewhere.

Great post! I hadn't seen this yet. Time to schedule a service with the dealership! Thanks!:thumbup:

You are the man :thumbup:

I was at the dealer yesterday and this was one of the things to look at. They said it will probably be mid Sept - Octber time frame before they will have it.

thanks for the heads-up! :thumbup:

I was in the habit of kicking over into manual 5th gear when this would happen and thought it was just a 'quirk' I would have to live with. Nice to know there's a fix coming.

Hi Maxey! Thanks for bringing this up. I was just fixin' to dig it up myself as I'm taking the X3 in for 15K service soon. It's still going to be a few weeks but I'll try to let everyone know how it goes. :thumbup:

Hi Ishniknork,
there are http://www.alldata.com/tsb/BMW/index-post.html three fixes listed here so hopefully they will get the right one.

I had it done at our 15k mile service, or so it said on the work order. I haven't really noticed much difference in the way it shifts.

Hi Rick,
Had the mod done will check this on saturday as I have a slight hill were it allways gave me grief so will let you know-- on another note had a click on closing the moon roof , the dealer is going to replace the roof again 2nd time with a modified version will keep you posted. didn' even have to get difficult

Good luck. I took a look at the alldata page of BMW tsb's. I feel so lucky. I wonder if all other brands of cars have this many bugs.

Mine seems to be holding 2nd and 3rd, even 4th longer than it used to even on flat roads. This could be partly due to the adaptive transmission control but when I start off uphill it seems to get stuck in 2nd or 3rd and I have to let off the gas for a few seconds to get it to upshift even though the road has flattened out or even started going downhill a little.

It doesn't happen all the time but you can sure tell when it does. I'm hoping the software update will fix it.

Same here had the wifes X3 updated last week. Since I rarely get to the drive the vehicle, except maybe on weekends , I cant really say whether the shifting has changed. Hmmm.. Does the tranny have to adapt all over again to driving styles?

I did punch the the car/sav, however we want to call it on my way home from the dealership and it did feel that it revved more freely up to the redline now ....I love it!

I had the service bulletin done on my 06 X3 this past week during my one year service at only 5575 miles. I notice a big difference when going up hills. I took the car up to catskills Mts this past wked after the service and it work out great. Also notice that it pick up a lot faster, but got to test some more to confirm. Highly recommend to get the service bulletin done. :iagree:

I got to drive my wife's x3 over the weekend and did notice the difference in shifting. It is much better now and does not hold on 3rd as it use to on slight inclines , I also observed that it will automatically downshift to a lower gear , then having to depress the throttle ever so slightly for it to downshift over steeper inclines.

Hi evryone--- yes had the mod done immediate improvement will shft up much quicker only in D other modes are all ok
Maxey

NOT happy with the upgrade so far, transmisson does shift up when it's supposed to BUT now it down shifts when it doesn't need to :banghead:

reminds me of an S10 Blazer we had in the early 80's
hhmm
must be because the X3 has a GM transmission :thumbdown :thumbdown

That's about the same result as I have had as well. On flat terrain I drive in "D". In spirited driving I drive in "SD" and when on varying elevation hiways I drive in manual mode so I can down and up shift when I feel is the right time. the 5 speed Auto in the 00 328 was a lot better at figuring these things out.

Hi Folks:

Help Please ....
Anyway someone can please cut/paste the service bulletin from the "alldate" website ... because when I hit the link to "alldate" website ... I get the homepage but can not find the BMW tab ???

There was a previous post that identified a BMW service fix ...
GM5 Uphill: SI B2 40506 (delayed Upshift may occur uphill in 3rd or 4th gear).

Is this the same fix as the one on the "alldate" website ???

Thanks

Same one. Sorry, for some reason I can't access the Alldata site anymore either. Looks like we'll all miss out on future BMW bulletins :(

Here is the bulletin. It seems they have figured out that it was possible to view the documents without login...

Just a thought, maybe there should be a section in X3World.com for bulletins where we could upload all X3 related ones we are able to find or run into? Then again, there really are not that many anyway...

Many Thanks for the Bulletin.
Cheers :thumbup:
