If you live in frigid climates you may experience that the valvoline PS fluid gels up. The ATF doesnt - it does gel but you need to get alberta level cold.

benz recommended ATF at that time of manufacture, you can find this exact fluid at Napa for under 10 dollars, or if you want another good one its motorcraft mercon V, it has very good antifoaming but has a downside, it smells like eau de skunk.
