have 2010 escape 160000 miles tranny fulid is dark brown red not burnt smelling! is Valvoline Multi-Vehicle (ATF) Full Synthetic Automatic Transmission Fluid safe to use? or should i just use what the ford dealer sells? i am sure that it would about twice the price of Valvoline ! i will not flush tranny but would drain out what comes out, witch should be about 5 quarts.
