Same symptoms are not always the same problem. My first step is always to have a qualified BMW tech check for codes and diagnose the problem, if I don't have the software to do so myself. Cheap investment when compared to trying 'stuff' to see if anything fixes the issue.

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

Looking forward to an update after session with specialist.

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.

In your case since the BMW dealer created the problem, I would go back to them to find out why that happened. They may want to do diagnostics but you can leave and get a second opinion and second estimate of the cost to fix, only paying for the diagnostic time if updating the software a second time is not the fix.

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.

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.

Interesting, and the rear bushing repaired has solve the problem ?
