    Did it happen "suddenly"? or had it been making noise for several days?

    Yep, just went into neutral and that is it. No other signs. the truck has 150k miles only.

    I'm thinkin the driveline speed sensor and the engine speed sensor had a disagreement over something..............;)

    Low on gear oil for a bit is all it takes to wipe one out?

    Hello Pal22g,

    it is good transmission until it breaks then you will have troubles. It has 5 sensors if one has an issue you can't move... In my personal opinion, I would not even look at ultrashift option even if somebody will offer free replacement. Downtime is my biggest concern!
