Im planning to take my baby this friday to get the tranny fluid changed. I have the filter kit which I ordered from Partsshop. My question is, do I need to use original MB tranny fluid, or should my mechanic use aftermarket fluid. The fluid seems to be fine, but i want to have it changed for a peace of mind. Should I have the fluid changed, or wait for another 6 months or so?? Some mechanics told me not to mess with the tranny fluid if its fine, because if you do, you will just make more problems. Can anoyone elaborate on this? Im most likely gonna change it this friday...
