hey, im new to this site and actually to be honest this is my first truck, it is a 1986 f-150, its done great umtill i changed the transmission fluid, now when i go to take off it seems like the gears slip. like it kicks into neutral, it only happens every now and then if i take off to fast. any help would be nice. thanks

Did I read this wrong. Castrol high milage. Isn't that a motor oil and not tranny fluid.
