Hey Scotty. Love you brother. I binge watch your channel and love your honesty and loyalty to being a moral upright man. I recently was in a wreck that totaled my 2003 Honda civic 2 door  manual trans. I had pelvis surgery, broke ribs, sternum, and eye socket. So I'm in a wheelchair for three months. I cannot work on my car like I usually do and I just bought a 2003 Chevy trailblazer 4x4 with 205k miles.  I believe it has the 4L60 trans and it has a 4.2 liter engine. I would love to bring my car to you to have you look at it as I only trust you to tell me what's wrong with it. I have the money to pay for diagnostics if your available to do so. the service engine soon light came on the next day and code p0440 came up when I had it checked at AutoZone. I believe it's the purge valve getting stuck because the gas mileage is down a little and uses more fuel than it's suppose to but not much more so I'm sure the fuel trims are high. The transmission takes just a little bit more rpm to change from 2nd to 3rd gear. I would love for you to look over my car and telle what I can do to help it last longer and have you work on it if it's something I cannot do. thank you for reading
