Low rpm rumble

[andrewb24]

I have a 2020 Silverado with 5.3L V8 8speed transmission and I think mine has just started doing it and I have 43000 miles.  My ex wifes 2015 tahoe did it but I couldnt ever tell it did but she sure could.

My dealer must have found the last one with TCC slip however it did not fix what I’m feeling. The only person who I’ve come across that said it fixed was those who replaced injectors. GM does

not appear to offer that as a solution.

Someone in warranty claims is doing their job. I tried to tell my dealer that the only report I’ve seen of resolution are injectors and they just laughed at the “social media mechanics”. I stated, no these are owners of your vehicles that know when it’s fixed and what did it.

Hilarious seeing that bulletin exists.  And was written...by GM.  

 

Find another dealer?
