 What's this Mercon deal, anyone know if this stuff will work OK, if it will
 damage stuff, and if I should really spend $9/qt. instead of $3 for regular
 ATF. Thanks, tim

Mercon has to do with Ford transmissions.  The different fluids are slightly
diffrent viscosities and the dexron uses a slip additive for smoother shifts.
 Newer fluids and especially synthetics are being rated for both
applications.

BTW-Transmission fluid will not make much diffrerence in engine starting.
