Seen a couple post about transmission fluid change. I can tell you this: Our non dealer professional said it needs to be changed every 40,000ish miles and that was because ours had 100k miles and shifting was making vibration loss of power stuff. We did it and it was like new. I wonder how many cars are dumped when that starts.
