My car has gone 203000kms and wonder if it needs new auto fluid. Don't know when was last time done, bought used in 1992 and no fluid changed so far. The trans has a very long twisty dipstick, can I pull this out and check to see if its ok? My newer 1997 C 180 was bought used in 1994 and has 226000kms now. No idea if the trans fluid has been changed at all, I haven't so far. Is one required or just leave it? Is there also a dipstick like in the 1994 model or not. This one is the 5 speed electronic one.
