I reconmend using Redline MTL Fluid...I find it better then the ford honey or the Tranny Cocktail. But again, i have Terry Haines Bulldog tranny with the upgraded flow chanels. But form what i researched , with a stock MTX, the Redline MTL would provide more than enough protection for your trans.
Givin its 12 dollars a quart in my area, but it is well worth it...that may be some thing to look into before you decided to chose a your fluid.
