<<auto tranny fluid as it's power steering fluid? Dexron III OK for both?>>

Yes, I have used Mobil synthetic ATM fluid now for almost three years now.  
It is DEXRON III compatible.

It was hard to find in my area.  Autozone was the only store to carry the
synthetic Mobil ATF fluid.

I have changed the fluid twice.  The van has @119,000 miles and does not leak
a drop from the power steering (I have not had to add any ATF fluid to the
power steering since I have owned it now).  I put in the Mobil at @70,000.
