I have seen the Dexron III-H, I think AC Delco offers one. I wonder if I should stay with the non synthetic or move to the synthetic Dexron VI

I would still do the oil change by flushing the whole content especially if you are going to Dexron VI which is also compatible and has better wear abilities. This can be done if you have the vehicle on stands. Personally I think these myths about dangerous oil changes are mainly based on cases where someone has tried to rectify an already faulty gearbox with an oil change or the oil change was done wrong and there was too little oil in the sump (not filled while engine running).
