From everything I've read out ATXs use Mercon/Dexron III ATF. From what I've been able to find it appears that Ford doesn't recommend Mercon V for out trans. OK. Most oil companies that make Mercon V say it's applicable wherever Mercon V and Mercon are called for. ?
Can I use either one? Is there an advantage to the extra friction modifiers of the V (I know the extended temp range is better)?
