my automatic transmission is making a funny noise lately. It sounds as if a wolf is hiding inside the transmission and is howling proportional to the rpm. It does not matter if it is in Drive or Neutral it is always making that sound. I am sure that it is the transmission not the engine. Additionally, the atf is somewhat dirty (visible when wiping the rod - changed at 70.000km).
Does anybody know if there is a need for a repair? The transmission is working perfectly (aside of the wolf), the car has 120,000 km on it (1997 model), 80% of it city traffic.
