I think the original engine software had a glitch in it.

If it keeps running like this, I'll never get rid of it.

Glad to hear that they have made progress with it, and that your trip
went OK. Towing across country with that kind of weight is a good
test.

Does Ford recommend towing in overdrive? I always make a point of not
doing that although I'm sure it costs some fuel mileage. You have
more torque with a diesel of course than I do with a relatively small
displacement V8.


Ford's new transmission for these trucks came out in either 2004 or 2005.
It has a tow/haul mode, which I use, but it does not lock out overdrive like
the older ones. I like it a lot - it behaves similarly to an Allison auto
transmission, downshifting based on speed and brake pressure, plus holding
in gear longer while accelerating.
