Hi all,

I believe this post to be somewhat unique as I have been searching online for this issue and have not seen what I believe to be what my Tahoe is having when it comes to this sound and acceleration.

When I am already driving and accelerate, there is a noticeable ‘plink’ or ‘tink’. It happens once - in other words it’s a single ‘plink’ or ‘tink’ not a re-occurring one.

It happened rarely but now with over 88k miles it’s happening more.

No other clicking or tinking sounds happen leading up to or after this sound. Its just the one time but happenes during each cycle of acceleration.

I can hear it in the cab and if my windows are down - it can be heard.

Thank you for any insight about what this could be or what I could advise a mechanic to look for/try and fix.

I had this on my 2015 Yukon Denali and they replaced my transmission . Early 8l90 units had some kind of clutch clearance issues. No longer does this for me. Changed trans at 15k miles.
