Anyone use Havoline ATF? The grocery store has it of all places for a resonable price... I've always used Havoline motor oils, so I thought about using 3 quarts(for the Mustang's manual tranny.) Blue bottle Valvoline is the other option(Maxlife is a little too thin in my limited experience.) What's the normal operating temps for a manual tranny using ATF, assuming "normal," mixed driving? Thanks guys.
