2015 Yukon XL Denali Low acceleration grumble sound

[Doubeleive]

also never heard of the transmission temp having a single thing to do with fuel economy or reducing emissions or anything like that, sounds like a made up story to me.

I'm getting the same noise, smh. Currently at ~116k miles.

Thanks for posting

Did yours end up being the same issue?

I had an issue with the trans fluid level being low after a flush and it made a weird growling sound occasionally at first under light throttle. It progressively got worse and I took it back to the dealership and they found it was over a quart low. Hasn't made noise since.
