    6AT Transmission Whine

    Wanting to know who else has an audible transmission whine on deccel and moderate acceleration at low RPM (Alpina D) when wind noise is low. Maintaining a constant speed the sound isn't heard. Car has been doing this for awhile now and I originally thought it was my differential, however when the car is in N the sound goes away. No slippage, temperatures are all in check, and no other adverse effects. Maybe it's a normal characteristic of the trans?

    Thanks.

    Yep, me. 95K miles. Not super noticeable but lately I have thought the whine was becoming more evident. Nothing else seems amiss.

    Fluid and filter changed at about 65K miles. Used Mercon SP for the fluid.

    Guess it's a sign that you should get a real LSD -- Wavetrac, OS Giken, etc

    My guess is the sound goes away in neutral because the diff is no longer under load.

    I have an original E82 AT sattelite lying around in the attic somewhere if you're interrested.
    22k miles on it.
    Since I have my Quaiffe I have absolutely no use for it.
    There are two theories to arguing with women. Neither one works

    Thanks for the offer. I will PM you later. Noise is the diff like I originally suspected.

    Yes that would be my guess as well but he doesn't seem to have consistency to this. Regardless, he wants to swap the diff.
