  1. I have a 2017 Silverado Z71 with 73,682 miles . This problem started back in January. The truck will die overnight. After a diagnostic I have found that there is power going to my F40UA fuse. The truck shifts fine and drives great when it is running. As soon as you turn it off you can hear a ringing of electrical frequency of the transmission module still on. I have pulled the fuse of the F40UA from under the hood and put it back in after the truck sat all night with it out in and it will start fine that’s how I am sure it’s the F40UA fuse transmission module. My question is what could be keeping this module on the relay has been tested and it was fine. Please help I am losing my mind. Thank you - Bryant
