I updated first post.
Edit: Cant change original post.
Update.
Changed ATF, filter and dropped the pan Last Sunday (7-28-19) with 50,548 miles on the truck.
Oil filter looked very similar to the one in original post.
Pan looked great! Only shmoo was on the magnet and no build up of any kind anywhere else. Grey stain is left over from water when I tested my new weld in drain plug. I left water in the pan for few days to make sure it wasnt leaking.
