For those of us that just bought a used Silverado, I have a 2014 5.3L LTZ. I want to share the dealership costs with everyone. I had the transmission fluid and filter service done. I was charged $350.05. $132.12 in parts and $217.93 in labor. I was going to do it myself but I decided to be lazy and pay, I just dont have the time these days. I have no issues on my transmission at all, just bought the truck with 68k miles and now its at 75k. Never know if the other owner treated it like I do. I live in Montana.
