The trans is throwing a trouble code when the tow/haul flashes. You usually get a temp spike on the trans gauge in dash when the TFT sensor goes bad, but I seen instances where people reported this was not so. You don't need a pan gasket, the factory is reusable, and you don't need a internal filter either. You don't have to replace the harness unless it is chaffed. You do have to keep your face clear when you pull the sensor out because a few more oz's are going to run out. Needle nose pliers seem to work well when pulling the sensor down after it's turned 90 degrees. You will need between 8 and 9 quarts to replace what drained out, and it might be a good idea to replace the external filter at the same time. All this is a fairly easy job which will take 1-1 1/2 hours taking your time.
