Transmission whistle

[Tkugs]

Looking for some help with a transmission whistle noise. I have a 2021 Gen3 with 9k miles on it. The transmission was overfull from the dealer which initially caused overheating and random up/down shifting while cruising at highway speeds. That issue was diagnosed and corrected and things appear to drive normally now.. However I now have a very loud whistle sound ALL THE TIME, and I cant stand it. Dealer says it's normal and I'm telling them NO WAY! It's so loud that my passengers and I can hear it over the radio!

Here is a short clip of the issue. Starts off with normal engine noise but starting about the 20 sec mark you can hear the whistle getting louder.

I'm curious if anyone else has the same noise, and if anyone has figured out what it is and how to correct it?

Thanks in advance.

If you can hear it over the radio that's nuts. With my new transmission in my 22 I only hear it ever so slightly with my windows down and when the trans is still reaching operating temp. What I wish wasnt still happening is the random thud/clunk when downshifting coming to a complete stop.

That whistle is not normal at all, especially at that volume. I’d try to visit another dealer if you are able to and take a tech for a drive to demonstrate the noise. Perhaps they botched the original service when they corrected the overfill? I also have the clunk when coming to a stop, especially a rapid stop. It’s normal apparently (drove someone else’s 22 raptor and it did the same thing) and as far as I can tell it occurs randomly. Some days nothing, some days it happens when the tranny is cold, some days it happens when the tranny is warm. I have 2k miles on a 23.

That sounds more like turbo whistle than a transmission noise. Does the noise get louder as it builds boost?

Just saw this bout GM 10R80 trans on the ole Tok.

I have the same clunk too!

I thought that was possible too but it does not appear to be the case.

That’s a 10L80. Haven’t seen that issue on 10R80. They share a design but they’re each built to their respective manufacturer’s spec in their own plant.

Damn. Learning everyday. Thanks sir.

I have it on my R. I agree, shouldn't be hearing. It reminds me of engine noise feedback that you would get from stereo systems back in the day. Wasn't sure if it was the supercharger wine also.
