Transmission problem, any ideas ???
Mine is an 2001 X5 3.0 with only 70k miles. Started having an intermittent hard shift on low acceleration when making the 2-3 shift, more noticeable when releasing the gas pedal. After some research, I found out that BMW has a TSB 24 51 00 (technical service bulletin) which actually describes this condition. The TSB prescribes a software update to remedy this condition. Today I had the BMW Dealer perform this update. It corrected the problem but created another one. Now I have a hard shift on the 1-2 upshift on medium to heavy acceleration. I am very disappointed to say the least. I welcome any suggestions. Thanks.

Try the reset procedure.
- turn key to position II - press gas pedal all the way to the floor, past the 'click' - hold like this for ~ 30 seconds - lift foot off gas pedal - turn key all the way to the right (i.e. start car) - drive forward Worked for me for 1-2 and 2-1 hard shift |

my 05 4.4i is doing the exact thing. I had the trans reflashed 2 weeks ago.Thanks for the tip!

gotta ttry this
|
I had same problem but only at cold start 1-2 and used Boston 4.4 procedure.
It works for me but only for a week or two and came back. Than, i've tried to let the car running a bit and start slowly...slight improvement. I've decided to full flush transmission fluid (transmission shop did this including torque convertor) Situation now is clearly better but still feel the kick but more soft...i will live with it. |
Hello. I have the same problem.
upshift 1-2 gives a blow and stop at traffic lights slams. The car has 58000 km, someone can tell me if it has been fixed. The first morning shift 1-2 is smooth. thanks |

That said, prior to troubleshooting or diagnostics, if you can do a reset (as mentioned) it is worthwhile to try as there is no cost. If there is a software update associated with your problem that is something else to do as it doesn't take long and is not expensive. There are strong feelings on both sides of changing the transmission fluid and filter as fixes. I am in the camp that changes the lifetime fluid every 50,000 miles. From the posts I have read here, changing the fluid after you have a problem, my guessing, has a 20-30% success rate. I don't know your budget or how long you have had this problem but unusual shifting characteristics, in any gear change up or down regardless of the RPM or if it is under light or heavy acceleration is not something to leave unaddressed. You need to know if this is something that is going to cause a more costly repair. There have been some posts where the problem has been lessened or is not present when the transmission is in sport mode. I would try that to see if the issue changes or is not present in that mode. If it does help, that would be something to lessen the irritation and perhaps keep the problem from getting worse until you can get diagnostics done. |

Hi, I was diagnosed that the change was in emergency mode, reset and test was conducted oil level and all good, but you better not go well and I order another appointment with the specialist, and informs the result. thanks |
titofre. So far you sorted out your problem HOWEVER you should (likely many X5 owners, but not all of them) proactively have your transmission fluid and filter changed.
The required specification automatic fluid will cost you some money BUT it will ensure that your transmission has a longer life, because you proactively took care of this now. A few 100 EUR is cheaper than a replacement transmission. |

Agree with Gregory, in my case, transmission fluid has been changed at 75kil, with Wynn's fluid (equivalence) but according to trany shop specialist the ol process is determinant to get a full success. Feel like the DYI fluid changed is risky business... Mine, specialiste used specific machine to clean 100% of oil + torque convertor....they used wynn's fluid (equivalent) http://www.wynns.ca/pages/english/e_companyprofile.html
http://www.wynns.ca/pages/french/f_m...rans.asp....so far 300miles later no problem.....and the 1@2 hard shift is better but not resolved since then....specialist was explaining that there is an electric signal in the tranny ( don't remember the name) that's getting weaker with time...creating this problem...but oil changed in my case helped....oil was so dark .... Can' t believe that life time BMW oil is real... Was not in my case...however as for the oil differential mine, after 75kil was like new. |
I honestly sympathize with the many owners sorting (most of the time successfully with good proactive maintenance) their automatic issues. I'm thankful (and prefer my X5 this way) for my 5 speed manual.
BTW, I also proactively exchanged the "lifetime fluid" in my transmission and NV125 transfer case with Redline MTL, and notice the significant difference. The old principle of "oil is cheaper than an engine" applies to many other components, I even change P/S steering fluid (converting to Redline) - cheap insurance. |
The specialist made the change oil and filter, but still does gives blow from 1st to 2nd and to stop. The specialist told me to take you for a programming change, to see if that solves anything.
A greeting |
I have the same issues with my 2006 x5 4.4i. Has anyone looked into checking to see if the rear bushings have gone bad? These can hit against the car and cause this problem. I'm having mine replaced as after much troubleshooting, this doesn't appear to be a problem with the transmission or software. Same symptoms: the car hits or kicks hard from 1st to 2nd gear.

My 05 4.4i had similar transmission problems (100k miles):
To try and solve this I first did a change of ATF fluid using RedLine D6 (approx 5 quarts). After this all three problems were still there but were noticeably less. That was a good start, but I had hoped it would help even more. The next thing I did was to "reset adaptation values" using the DIS V57 software. This is the page showing where I did this in the software. This worked miracles and completely resolved the first two problems I had. After resetting the values, I was still able to make the 3rd problem reappear, but it was significantly better than before. There is another option on this page to "reset the control unit" in the transmission, but I am nervous about trying that. I am quite happy with how resetting the adaptation values has fixed most of my problems - this almost seems the same as rebooting your computer after it has been running for weeks. Everything works better as the computer resets a number of values and it seems to run more smoothly. |

I'm interested to use the software DIS V57 but i'm not to familiar with this...how it works ? Thanks |
Whitecat - DIS V57 is part of a software package that you can use to read error codes, diagnose problems and alter software parameters on your BMW. I purchased one of the software packages from David Wragg in England and installed it on my laptop. I have used it several times to diagnose problems with my PDC (parking distance control), error lights for ABS/DSC and all my transmission problems.
It is really helpful software if you are trying fix things yourself. Rick |

Whitecat - you will need the one that also has the cable that connects to your OBD II port under the dash. See here

A reason to go this route is, if you have any install problems you will have help here. You will need a windows laptop. I dedicated a windows based laptop that had XP. Some versions of windows don't work or don't work as well. The DIS software takes a considerable amount of space so be sure you have the capacity. The software will work on an external drive. |
bcredliner - thanks for this information. I purchased from David Wragg and he provided assistance to initially get the software working, but has not responded to any of my queries for any additional help.
Getting help through this forum is a great reason to go with your recommendation. |
Thank you so much guys ! :thumbup:
