Just hit 53K on the clock, I use sport mode for slowing down and no problems thus far. I spoke with service rep at Thompson BMW about changing trans fluid and filter ($421 job, $200 for fluid). He asked why and said they serviced many BMWs over 100K and don’t change the fluid.

I know the parts manager at a BMW dealership in NJ for 20 years and he told me I should think about changing the trans fluid at about 75K.

I’m going to have my changed at the 60K service.
