OK - first i want to apologize because this poll would be a lot different for the track rats. I did not allow for you folks, and you are a large part of our audience/community , if not the majority. Still, this is about how often we change out our transmission fluid. I was surprised to see the 45k mile interval in the maintenance schedule. I know most do it more often than that. So, where are our intervals - when do you change yours?
