And are they easy or hard to install? I have a BMW software loaded laptop with allll the goods (no WinKFP tho) and I'm wondering if I should go upgrading modules or live with what I have... anyone with negative stories? Like Bricking...

In my case, I knew my tranny was OK (it was serviced not too long ago, and had some minor parts changed). All of a sudden it started to have the 1-2 hard shifting. Really bad. I tried connecting the laptop, it would recognize the car, it would communicate with all modules except the tranny, no matter what I did. This wasn't my first experience when the cars modules would get "corrupted/buggered up". So I removed the battery cables, touched both leads and re-attached to the battery. After this, I was able to communicate with the tranny module and reset/upload the latest software. With the ZF 6HP26 tranny (facelift vehicles) there is a caveat: These cars DO NOT HAVE the EGS module like the previous versions. The electronics module is contained within the mechatronics. This module is called different and you HAVE TO SELECT that module. I will revisit this post tonight with the correct name and a pdf I made on how to upgrade/re-install the software on these cars. There is a specific set of codes (numbers) you have to type in once you select the correct module (Progman SSS or GT1). I also read numerous posts on the net where people "had to" change the whole mechatronics module in order to fix the transmission jerk. What I think happens, is they didn't know about the pdf I will post when I'm back from work, and maybe didn't know about the fact that the transmission module is sealed inside the mechatronics. Basically earlier cars = control unit (in the tranny) + EGS. Facelift cars: mechatronics (which has the control unit + EGS which is called different in the same unit). If you somehow manage to select EGS and try to update that one in a facelift car, either you cannot do it, or if you can (I doubt it) nothing will happen, and the jerk will never be fixed. Resetting the adaptation values via the key in Pos II with the gas pedal all the way depressed for 30 seconds will NOT address the issue, because in this instance, the car also cannot communicate with the module inside the mechatronics. As I said in order to reset it, you take off the battery cables. These corruption of modules can happen on any car that might exhibit a slightest battery drop combined with I don't know what - probably a sudden big electric consumer that kicks in at that particular moment. As I said, I had this happen on 2 of my cars (e46 & e53). Also, this issue is probably why BMW switched to the awkward "battery registration" on newer cars, because they have an extra module that keeps tabs on the state of the battery - probably that module does not allow electronically to get modules corrupted by lack of electric juice. I will post later the correct procedure on how to reset the tranny and get rid of the 1-2 hard shifting. It worked great in my case. Cheers

Dorin, I have to say, I do not have any problems with shifting, so I should have stated that, but I hear of guys always updating their software for some reason.
First off, who is making these updated softwares, and are there any reasons to upgrade a software IF the vehicle is not displaying any symptoms? I'm not worried about better anti-virus/security features like you'd see on a computer, but figure maybe the software COULD be of benefit somehow since it came out for some reason...

When the 6HP26 tranny came out and was installed on various BMW iterations, most of these cars exhibited the 1-2 hard shift issue. BMW tried fixing it with I think 1 or 2 different software which failed. The last version of the software, however fixed this hard shifting issue. I am not sure which the number is or what year it was (sometime between 2007-2009 I believe), but if you have the latest GT1/INPA/Progman SSS, then you should have this version. When I re-flashed the tranny, I know I had the latest, but as I said it "glitched" and went in the 1-2 hard shifting mode, but I omitted to write down the software version.
If the vehicle runs fine, don't touch it. If for whatever reason it starts to exhibit the 1-2 hard shifting pattern, the first step is to re-flash the tranny module. When doing it with the latest GT1/Progman SSS software, when programming, the software will prompt you what software version will be replaced. In my case it was replaced with the same software, so I know I had the latest. I found the link with the 6HP26 issues and possible fixes. Tonight I will update with the pdf on how to program the tranny and the numbers you have to use for the different 4.4 and 4.8 transmissions.

ahhh so the software update file is built into the SSS/Program software?
So I have to update this laptop software every few years then to ensure I get latest files for updates to modules in vehicle? holy, thats weird. Thanks Dorin

Sorry guys for being late, but there was some playoff hockey I had to attend, and my Flames just burned the Canucks. I hope they will manage to burn them another 3 times. Go Flames!!!!
So attached is the pdf. If you ever have the 1-2 hard shift situation, and you know 100% that the ATF level is good and the filter is not clogged, just try to re-flash the latest software. This is for the 6HP26 transmission with Mechatronic. When programming, you have to select GKE (as opposed to EGS in pre-facelift models). The software later will ask for some numbers to process in the EGS (although you selected GKE), but this is normal. Read very carefully the attached pdf, because it spills out the exact numbers that have to be entered for a 4.4 or a 4.8 model. The pdf is SIB 24-01-06 SIB 24 01 06 Updating Mechatronic Software.pdf

2) How do I check the ATF fluid level on my e53, 4.4i? (internet says i have to use a lift, have car level, engine at operating temperature, RUNNING, and remove fill plug and should feel the oil with my finger at the bottom of this plug hole?) i can change my engine oil without a lift, i wonder if i can get to my tranny the same way to check it...  3) I'm far too scared to attempt updates haha, Doru, you're in Calgary, maybe you can do mine? I have the software but am too chicken.

To check the ATF level, aside from what you mentioned, you need to have the ATF at the correct temperature - it's around 50°C. You said you have the software, so it's just a matter of plugging in the laptop and monitor the transmission temp. Once the temp is reached, you check it with engine running.
Also, if you have the software, it's not difficult to update the car, just follow the prompts and use your head.

Doru, finally having to look at this software update.
So thanks again for all this info. that link about everything 6HP26 trannies states it COULD be a bad guibo... it MAY be my Guibo as well since I hear metal tapping anytime I shift from P/D/N... so I'll crawl under and see if thats a concern.
