hard shifting
 

Every since I bought my 2005 4.4i X5, the transmission would clunk as if it was not in gear. It would only do it on take offs. I have the steptronic. Recently, my mechanic inspected it for me and discovered that the trans needed to be re-flashed. I took it to a BMW dealership since only a dealer can flash the trans, they hooked it up to the computer and did find a upgrade which completely resolved the problem.Just curious if anyone else has had similar problems.

I believe a lot of people have gone through this. had my 2005 4.4i upgraded as well but it didn't make a difference for mine. So there replacing the tranny. The software upgrade has worked for some people but sometimes it doesn't help
