Trailblazer/Envoy P0740, P0753, P0758, P0785, and P1860 - first test

In this video you see the first step to take when dealing with these five transmission codes. This video is specifically for all five of these codes simultaneously appearing and its purpose is to be a diagnostic starting point. You see how to verify that your meter is properly grounded, and you see that the key has to be in the acc or run position to get power at this fuse. If the fuse is blown, and replacing the fuse fixes the codes, consider yourself lucky!
I try to title my videos appropriately, but if a search for one code took you here, a more thorough diagnosis is needed for that specific code and that is not shown in this video.
Thanks for watching, and stay tuned for more!
Due to the number of internet technicians out there, comments and likes are disabled. You guys would probably argue that I should have ran a 20ft jumper lead from the battery negative terminal and grounded my meter to that. See, it's easy to get on your computer and critique other peoples work, but when you don't create any content of your own, your comments are worth about as much as a gallon of piss. Thanks for the views though!
