automatic transmission flush
I'm due the 90,000 service on my 2011 F350 diesel. The dealer is recommending a transmission flush. Is this worth it, or are they just trying to make a boat payment?

Boat payment IMO. Ford recommends a drain and fill with external filter change, not flushing. Dropping the pan may be good but again, not recommended. And since there is a thermostat inside that controls flow to the cooler, the oil in any flush machine must be heated to open the thermostat so ask if that is done if you decide to go with their flush. And if they use chemicals to flush-run away! They cause more harm then good.
