Greetings. I am a new member to this site, but have owned my 2016 Pilot Elite AWD since May 2021. I'm the 3rd owner and bought it with 93k miles (now 120k miles). Right off the bat, I had issues with it that the dealer addressed, like replacing the engine push button and injectors. After that, it seemed like the car was good to go.
Then I started noticing a whining noise in the transmission when the vehicle had been running for an extended period of time and under hard acceleration. It appears to be happening in the shift from 4th to 5th gear. It's presently at a dealership now where they were able to duplicate the problem and use "chassis ears" to determine that it's the transmission. The technician is calling for a transmission replacement, because they don't do tear downs. However, this has become a point of content for the warranty company (IWS Acquisitions), who will not authorize the replacement until Honda tears it down and single out the offending part. They are trying to get me to take it to AAMCO, who reportedly will do it. They even called the place for me without my prompting, which is highly-suspect. They admit that AAMCO is a a fleet service provider for them, so it seems pretty obvious what's going on here with the maneuver. The contract does say that they could require further testing to verify problems, but I feel like they are using this to their advantage to avoid paying Honda and just pay AAMCO a lot less for the same result: replace the transmission.
I asked the dealership why they don't do tear downs and told them how I could see where the warranty company is coming from. They said they just don't and it's their policy. So I called another Honda dealer and they said they would do a tear down (at a possible charge of $500 if warranty wont cover it), but then said only manual transmissions.
Has anyone else heard of a dealership declining transmission teardowns? I have spent several hours today and yesterday reading up on this transmission on this very forum and other sites. Although I am pretty sure I've heard the "chirp" mentioned in this thread, the issue I'm having that troubles me the most is the whining. That seems like if I don't address it now while under warranty, I'm going to be out $7k later out of pocket when it catastrophically fails.
Also, I can't find where anyone in the thread actually had a transmission torn apart and then replaced, but I may have missed those details. So it seems like the automatic response by Honda dealers at least is to replace and not teardown, probably given how complex this transmission is. Is this generally the case?
