2005 S600 Transmission Whine
My 2005 S600 has developed a transmission whine at low RPMs (1000-1200). Most audible when driving speeds of 25-30 MPH. It's only noticeable from inside the car and sounds like it is coming from the transmission under the gear shift console. It is consistent even after car is warm and goes away at speeds above 30 MPH. It can also be detected when revving the engine to 1000-1200 RPM's in park.
Just had a transmission service where filter, fluid, and seals were replaced. This did not solve the problem.
Any ideas on what may be causing this?

The transmission fluid has only been changed once. I did put the car in neutral but to be honest couldn't tell if the whine was still there. Can the torque converter, transmission pump, and ABC pump be tested separately to see if they are bad?

I have a similar issue on my 2005 cl65 (low RPM whine). I can only hear mine with the windows up and it "sounds" like it's coming from the gear shift area. The whine on my car is coming from the Tandem (ABC/PS) pump though. At first I was pretty sure it was my transmission but after taking it in for service my mechanic verified that it was my Tandem pump. Mine appears to be coming from the PS side of the pump because when I turn the wheel from left to right it changes the pitch of the whining. When I raise and lower the car no whining.
Not sure if this helps but thought I would post my experience with a similar issue.

I did have my ABC/PS pump replaced in 2010. And thinking back, I did get a ABC pump warning light come on sometime before I started noticing the whine. I'll start with the shop looking at the ABC pump again and go from there. Then look at the torque converter.
Thanks for the input!

Kind of sounds like the pulsation damper in the ABC system in my opinion. My car had a whine in the interior of the car by the drivers feet I thought. The whine would go away if you increased the engine speed. It ended up being the pulsation damper that had gone bad.
Cheap fix really. I did it myself and it cost less than $200(part and fluid). Here is a link on it. Good luck and I hope you find the issue.

I'm wondering the same thing. Can they test the pulsation damper? The car still raises and lowers itself by pressing the ABC button and the pump is not leaking at all. Any guess on how much for a shop to replace the damper?

If the car makes a wining noise at low rpm's and low speeds driving it is the damper. As soon as you rev up the engine the noise should go away.

Have you checked your transmission mounts/engine mounts? My car was making a whining sound at low rpm. Had both the transmission mounts and engine mounts replaced as they were shot. Cured the noise (and very slight vibration)
