sorry to interrupt this intellectual discourse...

my question here is rather simple - my W202 has a normal Japanese/American AT style dip stick hole with a fat neck "seemingly" designed for filling the tranny up with fluid. But According to my friend there is NO maintenance period on these auto trannies from Mercedes. The thing I want to know is, if the fluid does look chocolaty, will a minute-lube style flush (tubes connected to drain plug hole and dipstick neck, then pump fresh fluid in to displace the old chocolaty stuff) is that still a "proper" way to flush a Mercedes transmission???
