Just purchased this vehicle (all orig daily driver) and want to be sure I'm going to use correct fluid. Always remember 'Type A'. Is current replacement Dexron/Mercon (progressive upgrade from Dexron, Dex II, III, addition of Mercon etc) correct for today.

 

i think "A" is called out by the factory. back then.. but i think the experts will tell you ATF +4 now days. back in the late 60-70s we used type "F" i had a mech i knew use farm tractor transmission oil in a chevy RACE CAR.. i have in the past run 2 QTs rear end grease in my 727-904s. but i dont think i would run it in my 2001 dakota 42.

 

Dex/Merc is the replacement for Dextron III .... ATF +IV has got fiction modifiers in is for the more modern transmissions and V has even more additives....Bill
