I have 07 TC five speed and it vibrates and all five gears only when I’m on the gas minute I let off the gas or hold the clutch in the vibration goes away but the minute I give it gas it vibrates again can anybody tell me what that is transmission or axles?

Your engine mounts are toast. Wife had the same on hers. Swapping them out isn't for the faint of heart. Three are pretty easy. The one on the passenger's side is a real PITA. Car will feel new again with new mounts.

My buddy is looking to get this TC as next project. He can get it for cheap but having almost the same issue, vibration when accelerating. We'll take a closer look at it after we finished installing the brake kit and black rhino truck wheels on the current Silverado project.

Could be a clutch-related issue also.
