I mean hooking it up to a machine. I had it done every 30k on my last 2 trucks and never had any tranny problems. My dad's always done it every 30k on his SD as well, and it has 180k on the clock with 0 problems. The same goes for my sister's '03 Expy....150k and still going.
Also, my grandfather had a SD that was identical to my dad's....same year, engine, configuration, etc, and he didn't believe in regular flushes. His tranny went at 120k. It could just be coincidence, but my family's experience with doing regular tranny flushes has made a believer out of me.
