Many folks in this thread seem to be very confused about what transmission is in their vehicle...
For the 328i/xi people: you most likely have the GM 6L45R, not the ZF box found in the 325/330. Make sure to double-check using your VIN or visual inspection prior to ordering anything. If you've got the GM trans and are looking for an excellent write-up on installing a Zip Kit, check out this post by labrador . It was helpful beyond description when I did this work myself. Quote:
But I digress. Your 2002 330 does not have either the ZF or GM transmissions that are being discussed in this thread. You have the GM 5L40E. |

I have been driving it around town on a daily basis hoping that any issues from sitting will "flush" themselves out. The battery seems to be holding a charge and starting every time. I don't want to take it too far till I replace the CV axle (part just arrived yesterday) as I don't want it to fail on the road. What is the sprocket image next to the shift indicator or the circle arrow with the triangle in the center of the display? EML?

The sprocket image indicates a transmission problem. There should be a diagnostic code associated with it if you hook up ISTA or some other BMW specific software to read it. The triangle with a counter clockwise circle is telling you there is a problem with the Stability Control / Traction Control. Again, there is likely a diagnostic code associated with it. All the lights on your dash could be resulting from a weak battery...maybe. |

Really depends on what you are looking to do. Just pull codes and reset service? Or, full service capabilities, including coding and programming?
http://bavariantechnic.com/ for basic code reading, clearing, service reset, and very basic coding. ISTA is great for dealer-level access, troubleshooting and maintenance. There is an assortment of coding and programming software available as well, which can be found in the coding sections of this forum. |

Guys I have a set of 7 ZF solenoids that are brand new in box. My dad got them for his 2006 325i but sold the car before fixing it. He paid $395 (have invoice) at CTSC a few years ago but it looks like the price came down some since. Shoot me an offer via PMs I rarely go on here anymore.

Yes, many months later! I have a 2004 e60 525i (140,000 miles) that is in flawless condition, except it is now doing harsh downshifts, 2 to 1 (or 3 to 2) when coming to a stop. Also, just standing still, food on brake, in sport mode, shifting from 1 to 2 and back creates quite a jolt.
I had the shop pull the pan, replace the filter, refill (level was low according to them) and reset the transmission. For $1400, they flatly said, "this will take care of that problem." Well, it didn't. Forward about a month, they would credit me toward a rebuild, or send me to a shop to have a rebuild. After reading this post, (thanks, zigsman!) I am going to go the solenoid route and mechatronix sleeve replacement to see if it corrects the problem. I also notice on the site they are selling the solenoid kid for under $300 now. I am having a local shop do the work when they can find the time, but will try to let all know how it goes. Thanks for letting the e60 guy post. If there are any words of encouragement out there they "yes, KNKLHEAD, this will correct your problem!" I would appreciate it. |

Did they change the rectangular seal on the mechatronics unit? Also resetting transmission adaptations after a fresh oil change is not recommended unless you can carry out correct adaptation procedure. |

It was $1400 to change the pan and the filter and top off with oil. Yes, Expensive. They realize they owe me $1400.
They did not change the mechatronics sleeve -- or at least they didn't note it. I hope to follow up here when I can get the sleeve changed and the solenoids. |

I finally was able to pull the valve body on my 2006, 330xi and install a Sonnax Zip kit. It is imperative to get the number from the separator plate since the kits are specific. Mine was A052/B052 (Sonnax Part No. ZF6-6R60-ZIP). I purchased the separator plate and Zip kit off of ebay. There are some very good videos describing the details of the valve body on the ZF 6HP19. Not difficult but very time consuming and attention to detail otherwise you will forget where the check balls, springs, etc go. The most difficult thing was removing the old regulator valves from the valve body since they are very tight tolerances. The Zip kit contains exact replacements but contain an O ring to seal. It also contains the new style accumulators that have a spring for tight sealing rather than rubber, which wears out on the OEM. The only obvious things I found were the accumulators were worn out and the D clutch regulator valves were loose fitting compared to the others. Pulled out with no effort. Bottom line, this solved my 2-1 hard/delayed downshift. I did reset the adaptions and the transmission shifts perfectly through all gears and no delay when the fluid gets hot. I have driven about 100 mi so far and still good. |

What fluid are you running? My car ONLY likes ZF lifeguard 6. Twice I've had a shop put in different fluid (and only a few quarts) which caused horrible shifting and odd behavior. Had it refilled with ZF lifeguard 6 and at 166k miles it drives and shifts like a brand new car.

SUCCESS!
Hey, guys, while others tried other stuff, here's a post I made in another forum. I am not an e90 owner, don't tell anyone!
Hi, everyone. Paying it forward! I get so much info here, I wanted to go over my troubles with my beloved 525i with 140,000 miles on it. It rides as nice and any new car I have test driven, bu t who wants a new car payment? The issue was, while coming to a normal stop, regular p, fooon brake pedal, the car would jerk hard when downshifiting, I am guessing gears 3-2 and 2-1. It was driving me nuts. It felt as if someone might be hitting me from the back end and it was very noticeable. t also drove me crazy that mechanics would say, "I think that's normal." ARGH. I might also note when backing out of my garage, slight downhill, I had to press the brakes much harder than I thought I should, not sure if that's related. I took my car to an Auth'd BMW dealership in the State of NY (for now I will not say the dealership's name, as they've been very understanding. More on that later.) They said, no problem, we can fix that by dropping the pan, ensuring fluid levels are right and by definition, putting in a new filter (part of the pan?) and Transmission reset. I was specific when I asked (for this 2004 with 140,000 miles) "will this correct the problem?" Thinking, maybe I have to trade it in. Cheerfully the client specialist said, "Yes, this will work." Sadly, same issue the instant I got the car back. I took the head mechanic for a ride and he did acknowledge the problem. The services manager said he'd try to find me a deal on a third party that could rebuild my transmission. He suggested he'd offset further costs by $1400. We'll see. That's where forums like this are so valuable. I did a bunch of research on this issue and found quite a bit. This doesn't work, that doesn't work, this doesn't work -- but I found lengthy posts about solenoids and sleeves that looked promising. Fast forward. After reading tons and tons of info on my specific transmission (I think it's a ZF GA6HP19z.) I decided to buy a solenoid kit and mechatronics adapter from CTSC from Klaus, who was awesome. (I have no relationship to Klaus or this company except one-time happy customer,.) https://www.thectsc.com/products/sol...ft-36-115.html and https://www.thectsc.com/products/mec...p21-44-45.html., I asked around town and found a great (albeit extremely busy!) transmission shop called Buchholtz Transmission. Mark the owner is the nicest, most honest guy ever, and great/knowledgeable guys in the shop,. Any way, I told him we were in this together, I wanted to have him install these two PNs, I'll take the chance, but needed to wait quite a while for him to fit me in. (Understandable -- these guys have unlimited work!) He finished my car this afternoon. Wow. No jerk,!!!! Smooth as silk! Downshifts are unnoticeable coming to a stop (the way they should be!). I hugged my wife when I got home, told her I now don't want to buy a new car (that she gave me the thumbs up to do!) Now, it could be new fluids, the reset, the solenoids or the mechatronics sleeve -- but this combination seemed to do the trick. And yes, could there be a further issue? Sure! But at least we know the transmission/hardware is fine! I hope this helps someone else out there. I found this info on an e39 post in another forum. (Mark, you are a great guy and the world is better because of you.) " So: Before you spend $5000 on a new transmission or a rebuild, this may work for you, too. I am looking for a credit or compensation from the Auth'd BMW shop for my $1400. They've been very good to me and I am confident they will do the right thing and possibly credit me. I hope it helps others. "The best car on the road? One that's paid for." - free advice |
