What do you use in your T-45? I have to change mine and I was wondering.
mercon 3??? you mean dextron 3... ford has replaced mercon with merconV for the t-45's.....Motorcraft mercon=GM dextron3....the t-45 has paper friction on the blocker rings and needs modern ATF to work properly...
Walt from promotion told me that any mercon 3 ATF will work fine for the T45's. He said don't waste your money on high dollar mercon III or V's. They're all the same. He built my T45 and I anally rape it during shifts.
