ok so im pulling my motor and have the tranny out and just kinda thinking ahead, im wondering which is really better? atf or the gear oil? a mechanic friend claims that ford said to use atf because it improves gas mileage slightly and makes it easier to shift in cold weather (thinner fluid), is it true or is it better to use the gear oil? the mechanic also claims the gear oil is better because it sticks to the gears better so heres the question.. which is really better, i have 3 quarts of each sitting in front of me, which do i put in?
i know its been asked a million times, but i cant seem to find a real anwser, which is really better, my fresh rebuilt t5 is on the line here (i know its still a pos tranny)
