Sound coming from transmission when downshifting

[DontTaseMeBro]

Hi all. I noticed that when I'm decelerating in my '22 Yukon, I hear a clunk emanate from the transmission as I'm coming to a stop(happens around probably 25-30mph). I don't feel it, downshift is smooth as always. But I do hear it when the transmission is downshifting into one of the last gears. Anything to be concerned about?

What transmission do you have in your Yukon?

Far as I know, only transmission available in the Yukon in 2022 is the 10L80...maybe different between Diesel and Gas engine, but I think both are 10L80

I’m not hearing right as I’m driving around at the moment. Could be that the transmission wasn’t fully up to temp. I’ll check them the next time I cold start the vehicle.

About to hit 50k on the odometer so fluid will get changed here soon.
