+1 Start by changing the fluid and work from there...

I have 78k on my 2005. The slam started at around 65k. It's been to the dealer three times, never been able to replicate at the dealer. It's been probably 4+ months since the last time it did it. Seems to be worse for me, anyways, during colder weather. I think the dealer did the trans reset on it once, but that was it.

If you search here and the other e60 forums you'll find a lot of info on the problem. Seems to be varying degrees of issues, but the lack of a fault code seems to be the biggest issue with getting CPO and third party warranty to recognize / handle the issue. Also, it seems that the issue is not limited to 2004-2005 545 but it also affects the 550s, so take heart in the fact that if you spent even more money to get a 550 you might have the same situation!

Resolution seems to be - fluid / filter replacement, transmission reset, megatronics (sp?) replacement (about $2k), and finally trans replacement in extreme cases. However, it seems many get over 100k miles on the trans without significant issue. i am hoping to keep mine going for a little while longer. We just love the car and don't want to get rid of it.

I searched for issues before I bought mine and didn't see this come up and I didn't have the problem for about a year or so after I got my car - a CPO that had 30k miles.

We love the car - especially after the billy boat exhaust install and y-pipe resonator removal - verroooom, verrrrrooooommm. But, gotta agree that this is not the type of issue and lack of response I expected out of BMW ownership. We've got two BMWs right now - the 545 and 335. It's unlikely we will own another BMW, maybe a lease, but thats it. They've made the cars into appliances for the leasing market and are devoid of ownership concern - in my humble opinion.

My old 2005 545i had that same problem, and after MUCH effort BMW did eventually replace the transmission, it took time but they did it! Just be VERY persistent and don't settle for any excuse where the slam is concerned.!

Could be a corruption of the gearbox adaptation values

Mine was doing it after an oil change , I had used INPA to measure the gearbox oil temp during the oil change and had frequent data flow errors that may have caused the adaptation figures to be corrupted

Mine was fixed through INPA

INPA
F4 E60
Transmission
Gearbox Control module GS19
F6 Activate
F3 Reset adaption values


go back to the dealer and ask for this to be done, it is a 2 minute job

I hope it fixes the problem for you

My gearbox is now smoother than I have ever felt it

Is this a permanent fix or just a software version of the "25 second transmission reset"?
I used INPA to monitor tranny temp during an oil change. Thanks for this info .

should be permanent, I won't know for a while as I have only just done the reset last night, but in certain gearbox software loads the corruption of the adaptation values is possible I am assuming the software load on my car is the one that suffers the problem, a software upgrade to a later version is supposed to cure the corruption problem permanently but this is only on the advice from another forum member

I have to report that the car behaved differently this morning; it's more responsive to throttle input, and accelerates smoothly and effortlessly. It?s just unbelievable. Thanks .
