Matic D/DexIII not tough ATF spec to meet. MaxLife Syn a readily available option, decent value in the gallon jug. Castrol Transmax Full Synthetic another option but now seems hard to find. Castrol Import Multi Vehicle another option. IMO, anything saying Dex III which would include the common Dex/Merc options like Valvoline or even Walmart SuperTech should work fine.
