Just got a 93 escort, but do not have the owners manual to know if it take Type F tranny fluid or mercon? Also my tranny fluid is really dark, almost motor oil color. Car will not move in any gear, do you think my transmission is toast? Previous owner could not recall if fluid was ever changed or not, she inherited car from her grandma who died last year. According to paperwork I have and odometer car has roughly 70,000 original miles...
