Hi,

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.

Is the sound a constant mid range whine. can you hear it at 40 mph????

 

[BerlinCSE]

yes, it is a constant whine but its pitch is proportional to the rpm - in idle the pitch is mid-low and gows up with the rpm to a high pitch above 3000rpm.

At 40mph I can still hear it - but since the noise of the tires and roads are noticable too at thit speed it becomes more difficult to hear the transmission whine.

But do you think this could be?

Howling Mad Automatic Transmissions?

Hi Guys,

Any follow-up on how the Tech Bulletin items performed? Did these actually resolve the issues or is there something else that ultimately addressed the problem?

Reason I ask is that I purchased my beautiful 9000 CSE Turbo this past fall and inherited the howling problem. At that time, I thought it was just the nature of the car because I didn't know any better. Since then, I've come across other similar models that don't have the problem, so now I want to get it fixed.

Any suggestions?

Cheers,
Enrique
