Fishinsinsation

So... I had minor vibration sometimes bad. I bought a low profile toolbox the other day, and have had a ride as smooth as glass, curious if the people with the vibration have a cover, or toolbox on the back? Maybe it's a fluke, but I'm thinking the 80lb toolbox is doing something, cuts down on the wind to the bed? Added weight? Stiffens the bed/frame? Maybe it's all in my head?

So, I have noticed that my truck vibrates a little while the transmission warms up, I have been monitoring the trans temp, and I get noticeable vibration until the transmission reaches a operating temp of over 180 degrees, after driving 45 minutes it reaches 194 and it's smooth as silk at all speeds, what's the issues with the transmission? Going to bring it up when I take my truck in to get a door ding fixed that was on it when I bought it Anyone else notice this issue?

Ok, question on this... I watched the you tube videos, and saw the cup of waters vibrate, at idle my water vibrates a little, and stays constant until I hit 65mph, my dad's been going threw vibration issues with his 2012 Toyota tacoma crew long bed, and said mines better than his but he still felt it, is some vibration to be expected on a full size truck, or is this not normal, I never noticed this in my last car (Honda civic) perhaps I'm just reading to much into it because of this forum? Ps I have 550 miles

I also have a 7/14 build I got soft wax flying up all over my truck, no rust yet but it is very soft and I'm able to remove it with my finger nail

Just got a 14 silverado last week, drivers side door sticker Says 7/14 hopefully I don't have the issues others are having, this is my first truck and love it, ps the colors tungsten, not black #trucklife Msrp was 46,510 I ended up paying 37,000+tax/license
