Anyone else experience rattling heard only at low engine speeds...sounds like loose metal on exhaust but actually bent torque tube and posssible replacement of torque converter...My C7 in shop going on 8 days now after being on the road just 3 short weeks...doesnt exude confidence on product durability

Had the same noise in my c6,it was a loose hub nut in torque tube,factory fault only had done 4500 kms,you hear the metallic rattle on idle if u rev it a little ova idle rattle goes away
