I'm curious about those of us with the sealed "lifetime" transmission fluids who've actually changed it? If you have, notice any improvements in operations, smoothness, etc... I see the sticky in the maintenance section, but I haven't seen anything regarding how many folks actually do change it, and post back the effects of doing it. I'm at 63k on my 05' v8 and thinking about doing it. I don't believe in "lifetime" fluids at all. They said BMW's never needed to be changed, until a flood of failed transmissions began to pop up. Now I think it's recommended every 35k miles.
So, who's actually changed their fluids?
Thanks all....
