Since I'm the original owner a mechanic has never touched this truck, I need to change the trans fluid and presently use Castrol for Ford automatic ( i'm sorry i ever took the Original mercon out ) The trans shifts ok but i recall smoother shifting , Does anybody know if you can refill the transmission directly under the stick with stick removed rather than using the fill plug ? and what do you other ford owners use in you manuel fluid changes ?:thumbup1: thanks , this site is very informative
