Over the last month or so, I just started seeing the check engine light
come on in the Durango.  The error is P0740.  I am almost positive it is
the Torque Converter, not the sensor.  

I would imagine this is an after-effect to the radiator explosion that
allowed anti-freeze to get into the transmission.  

Just as a last resort, I put some stop slip stuff in the transission fluid
to see if it will eventually have a positive effect.  It could just be the
fluid is still not 100% after that problem and this additive might help.

If not, the only real way to fix this is a new torque converter.  That will
most likely be a complete transmission rebuild - around $2000. 

Will see if the additive has any positive effect after the next month or so.
