One thing to make sure. Are you getting a rebuilt transmission or a used transmission? We deal with alot of warranty companies that won't do reman transmissions. I hope your dealing with chevy direct on this. I put a used trans in a tundra and a thousand miles later it came back with another bad trans, warranty company sent another used trans, customer traded it in at blades I think, white tundra with a deer smasher bumper on front.
