Why is this problem just now happening? I am wondering if some of the recent software updates have caused this problem? I have a 07 550i with 40K miles and it just strated to slam in the last couple of months right after I had a i-drive software update.

Cobra 427

Well, yesterday a different SA left me a vmail on my home answering machine saying, "Car's done. Come pick it up. The tranny was: NO TROUBLE FOUND... blah, blah, blah..."

This morning I called my normal SA, and he told me that they flashed the tranny with the latest software and can't reproduce the Slam or Torque Converter jerking. They tried to order a new tranny, but the shop foreman couldn't get the authorization from BMWNA, or some such authority. He further told me that the Regional Field Manager will be at the shop next week, so I can bring the car back then and see what he says (assuming the problems persist).

My plan is pick up my car tomorrow, drive her around, see if she still Slams and Jerks, and if she's fixed, then great! If not, I'll be back to the dealer next week.

Someone wrote on this subject, "be persistent".

And the saga continues...

And the car still runs great! No more transmission issues...

thanks.

Did they have to remove the tranny to replace the part? Cost of repair (assuming not under warranty)?

update: it has been a month since the software update. no tranny slam

Yes they did remove the tranny, They had the car for about 10 days... CPO = $50.00, not sure of no warranty cost...

Sorry to bring back old thread....
I have very similar issue with my car and not sure if tranny slam.

Driving at low speed tranny/ car jerks a little bit and rpm jumping until speed up. I do feel bit of vibrate from 20-30mph.
Mine is 04 525i with 89K miles. Didn't drop the pan but drain and refill tranny fluid at 75K.

Would this be a slam issue? would reprogram software fix this issue?

Plz help..... =(

You sure you did a drain refill correctly? I mean technically since you didn't drop the pan, it's just that a drain/fill....which means you replace the fluid you put in with new....which I'm assuming was about 4 liters? I hope you didn't mix fluids. I'd only go with an approved fluid for that specific tranny, (Pentosin ATF) and make sure that you fill it correctly.....running the engine that is and under the ZF guidelines for temperatures while refilling.

If you've been driving it and it did not do anything most likely you did everything correctly. Perhaps you have some incorrect fluid levels at the moment? Or perhaps you also need to just do a tranny reset.

i'm on my third E60 (2005 545(bought new), 2005 545 bought used in '07, now 2008 550)...BOTH of my 2005's had the slam...i only kept the first 2005 for one year, and the second one i had for three years...BOTH of them had this problem...
the best way i can describe it is this way.....
imagine driving through a residential neighborhood with many stop signs and you never really come to a complete stop at any of the stops....
as you slow down approaching the stop signs, but then begin to accelerate again without the complete stop...right as you accelerate it almost "confuses" the transmission and to ME it "slammed" into the gear after a hesitation of not knowing "which" gear it wanted....the result to you inside the car is a load noise, a "slam" feeling as if rear ended...it's unmistakable....if you have had you would know....
i was told WAY back in 2005 when the slam was newer in the posts that the "reprogramming" would help and it never did...i just ended up living with it...irritating as it was...although i got good at avoiding it....
on the second 545, purchased with 45k miles, within the first month of ownership i had my first slam....it was CPO and purchased with the extended warranty covering the wear and tear....again i went through the leaving it for two days with a "reprogramming"...but to no avail...i'll admit...on the second car, it did NOT happen for probably a year after the reprogamming...but eventually surfaced again....i used to cringe when not making a complete stop, as in approaching right turns at slow speeds or the WORST was coming to a red light that turned green before making the complete stop...i would tense up and go "LIGHT" on the pedal as not to "slam" it into gear....
i am one month into the 2008 550...with NO sign of this problem...i even tried to make it happen...but hopefully it's just one of the lucky ones with no symptoms...

cheers!
