I never said there was no connection between not changing the fluid and BMW's recommendations. On some models there is a recommendation to change the fluid at 100,000 miles, and on others there isn't. I said there was no connection between not changing the fluid and transmissions failing from lack of fluid changes.
I don't know that BMW did change their policy. That is a conspiracy theory. It is similar to the urban myth that BMW went to extended fluid change intervals only because they started paying for fluid changes in some markets.
BMW has had different recommendations for different transmissions. They changed their transmissions before changing their recommendations. I don't have a record of them going back and changing the recommendations on transmission models that were superceded, at least on the models I have owned. Perhaps they did, I just haven't seen it. If you have the BMW bulletin (SIB or TSB) that changes the interval, please post it.
