I heard MB modified their recommendations for new cars.... to change the fluid at 30K, then every 100K after that. The 30K services flushes out the break-in wear debris, then the transmission can see a more realistic 100K service interval from the fluid. Can someone verify this?

Personally, I'm with redcoupe and would recommend 60K-100K changes... especially if I plan to keep the car a long time and can do it myself.

kchemers appears lucky. Most of my friends who've had problems with their transmissions never changed the fluid.
