I have to agree with anyone who suggests changing the fluid. Fluid isn't made to last forever. Second and this is the biggest issue is the fluid gets dirty. That's the killer. I went to a BMW dealership today to get parts and starting talking with a tech there. I asked about the "Lifetime" statement for the tranny fluid and he commented that to BMW that was 100,000 miles. He was emphatic that you need to get it changed. Second on most automatic transmissions you have a dipstick and can fill thru that. This allows you to get the correct amount of fluid into the tranny (including whats in the torque converter. My 3.0I doesn't have dipstick. He stated that if you just fill from the torque head bolt on the tranny pan, you won't get all the fluid in that you drained out. Not sure as I have never done this but for those folks who have or those who are BMW technicians is this true? he commented they had a special hose that allows them to get into the trainy to get the correct quantity in there.

Any thoughts?
