My indy has worked on BMWs for 20 years and was service manager at a local dealer for 10. He told me not to pay him the $500 for a proper flush and filter change.. said he'd rather sell me a $5000 transmission in a couple years :-)
My 4.4 is going in tomorrow. I'm at 70K and mine shifts just a little harsher than I'd like. Even if the new fluid doesn't help, seems like cheap insurance.

HAH! My mechanic, who used to work at local BMW stealer, told me almost exactly same thing. "Lifetime" in their eyes is the life of the warranty. Back when the X5 was under the maintenence plan, I asked the SM and was told they won't even do a fluid change if requested by the customer.
Originally my E320 had the same lifetime trans fliud, but then later on MB put out a service bulletin to change it every 60K mile IIRC.
