Can someone recommend a site where I can read and learn more about this.

Thank you for your time.

The issue I have is form 1-2nd gear and then shifting down form 2-1 it is really rough and sometimes it slams. The slam is so bad that it moves the car up and back like you are rocking it. I took if to the dealer again and they tested it could not duplicate issue. I ask the dealer to do a drive with me and I showed it to the shop foreman who said it is normal. I couldn?t get it to do it as bad as I have experienced it. The dealer is saying there are no codes and I can do a software update and it will cost me $400. I just paid $30k for this car and now I have to throw $400 in to it and that might not even fix the problem by the way the car is a CPO! I feel like this is a mistake and I will stay away form bmw in the future. I really expected better form BMW. Anyone looking for a BMW beware.

3. If there is no code - go to point 1.

Went through this couple days ago... and though transmission matched 100% BMW SIB 240305 - it did not show any codes so dealer SA said "no code - no repairs". I asked them if this is a common problem - answer NO. I asked if the can reset tranny memory - they said "no code- no repairs", asked them to update Sw - same answer - "no code.."

Called my independent mechanic. Just stared to describe the issue when he finished..." yeah heard that one - not a common issue , no code and no code - no work"
And he said _ MANY car with this tranny has this issue. Resetting "learning" memory will fix ~50% (90% show initial improvement but it tends to comes back in a month or so), next step is to update Transmission SW - this will fix the 80% issues ( bmw made improvement to restrict downshifting from 2->1 when costing and some people complain about performance after)
Unfortunately 20% have to have Mechatroinc unit replaced and this part costs ~ $ 1.5k - $2k (it dependents where you get it from - i.e if you buy from Tichner BMW (www.gerBMWparts.com) or independent ZF dealer for rebuilt unit ( http://www.thectsc.com/index.php?p=p...id=47&parent=0 ).

Press those stealer morons to update your software, it does take time and some nerves - part of over-hyped BMW ownership.
If software update doesn't help - it's your mechatronic unit, for this fix you need to fall on your knees and beg, and even that may not help.
F.ck bmw!

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.
