Hi zip439,
I had my transmission serviced by an independent Mercedes shop so I know it was on a lift. Chrysler says to service at 80,000 & Mercedes says 40,000 so I did the 40,000. Also the electric connector on my '04 was leaking. The connector has a small screw that can be broken when installing because of a tight fit. The replacement connector will not leak. That is all I can say.
