I have a 2000 C280, bought at 35m, 6/2005. Tranny has been a delight, perfectly smooth, except for that occasional dump into 1st gear when stopping, but this has been eliminated by leaving it in "W" mode versus "S" mode.

I changed out 2.5 ltr of tranny fluid via the suction method at 35m.
I dropped pan and changed filter and about 4.0 ltrs fluid at 45m.

Now at 70m should I

a) again just change filter and 4 liters of MB fluid for about $40

b) take to a dealer for a full flush and filter for $475?


Thanks,
