I assume you’ve never worked with any sort of production, then?Concerning the ATF warmers, why would there be what appears to be a mid-production year range of defective warmers? It seems the problem would have been introduced at the start.
Thanks. I do appreciate the sentiment. I'm hoping that Cerritos Acura (or I'll even try a Honda dealer) will be the key.I feel for you. The dealer service department can make or break a car ownership experience. I’m fortunate that my local dealership is excellent, and it’s honestly what brought me back to Acura. Having lived through crappy service departments with problematic vehicles it is now one of my key search criteria for a new vehicle. I overlooked the XC90 because we have one local Volvo dealership and they have a terrible reputation. Have you had any luck working with the service manager instead of the tech? My service manager implied they have a lot of sway with Acura on warranty repairs. I posted about this in another thread somewhere, but my 2016 had the same issue as yours, PLUS some really clunky shifts as though the car was dropped into gear from neutral. I bought it used with ~12k miles and I knew about the problems with that year and wagered I had coin flip odds it would be a problem. During the test drive I was surprised at how flawless it was. Somewhere around 25k-30k miles I started experiencing the dreaded chirp. I eventually noticed it happened at the same place each day during my commute and that helped me to reproduce it. You may have gleaned this yourself already but what I eventually figured out is that the car needs to be going at least 40mph, and in at least 5th gear (past the first dog clutch). If I slowed down to anywhere from about 22-25mph and then accelerated as you did in your first video the car would downshift from 5 to 3 or 6 to 3. That move always resulted in the chirp. By 33,000 miles it got pretty loud and the other symptoms were worse. I actually was nervous about the clunky shifts that it would just one day fail. I brought it in to my Acura dealership with a full description of the symptoms. They reproduced some and flushed the transmission fluid under warranty. They also did a few other repairs. They followed up to check on how things worked and I explained it was still chirping. I told them my fear is that I don’t believe that’s noise reflected operation as designed and I was weary about driving my two year old and (at the time) pregnant wife in the car. I explained I was fearful of a failure in the middle of the intersection. I asked if they would consider a ride along and the service manager agreed to come with me. I was able to reproduce the noise readily whether traveling in a straight line or turning. He was surprised by the noise and they took it from there. They ran lots of tests on my vehicle and eventually replaced the transmission. I think all told they had my car for a little over a week. I have roughly 5k miles on the new transmission and it seems like a different car. I did a little digging but I’ve honestly never been able to find out what causes that cheap. I was happy with the fix and didn’t really press it. But I read enough other stories to know that if it warrants replacement for other customers I needed to play the game to get it fixed. I am fortunate that I’ve have an excellent dealership to work through. My only suggestion would be to focus your energy on the dealership that is further away but helpful. Good luck and stay persistent. My experience says once it starts, it gets worse, so eventually you will end up in the same spot.
Cool keep us updated. I've noticed it is more prominent in the summer as well, so I'll pursue this again come June.Hey, just found this post! I'm in the same boat as you guys, with the squeak sound at 22 mph. Easily reproductible when ATF temp is above 100 F. I have a appointement next week for the dealer to look at it. Wil let you know!
Thank you for the follow up! Very glad you got it worked out and it looks like you even got a NEW transmission instead of a remanufactured one! I'm about to start a year long campaign to get my transmission fixed. I'll be sure to drive it to a good temp before meeting the dealership techs for a test drive to demonstrate per your 100F ATF info.Tranny replaced as well as warmer. No more squeak sound and the new tranny is really smooth!
The tranny model number is the same (1094 040023), but serial number is different (now 0085956, was 0145946). I found this date on the nameplate (01/08/20), so I guess i was manufactured January 8th 2020.

The warmer is same model but manufacture date 2019-10-10 instead of 2016-03-16.
According to the tech sheet, the condition and level of the ATF was checked during diagnostic and everything was ok. They ended up with the following diagnostic : "internal defect, automatic transmission to replace". Funny because they also replaced the warmer….
I purchased the OEM transmission cooler a couple months back and was planning to install it before summer. I asked them to install it while replacing the tranny and they did if for 1 extra hour (the only thing I paid for).
Hope this help!
