Hi, I have a 2016 silverado. For the past few months whenever I accelerate there is an odd grinding noise coming from the truck. It feels like it's right below my feet. It also only seems to do it when I'm cruising in a higher gear with my foot resting on the gas peddle or starting up a hill. I also check all the fluids regularly so they are all where they should be. Any insight as to what the problem might be would be appreciated.

 

any ideas? My 05 i just bought is doing the same thing.

 

I just bought my 2014 back in September and a few thousand miles into owning it I started getting a shake/shudder with a griding-ish sound only at certain RPM levels (mainly when just cruising about 1500 rpms) and it was a bad torque converter and apparently a ton of these trucks have this issue. Converter was about $300 and a buddy and I installed it.
