I have heard the BS about how changing the fluid can cause problems but I don't believe it. I have owned over a dozen cars and the ones that I neglected to change the ATF in caused me problems. The ones that I changed the fluid/filter every 40K miles went for years without a problem. It just makes sense. Of course you have to use the correct type and amount of fluid or you can cause problems.

Good luck.
That's exactly what it is. I changed the transmission fluid in my 2001 X5 at 108K miles. I had zero issues with the transmission when I traded it in at 126K miles last October. That's 18K miles over 18 months without a problem.
