I have a 2013 ford taurus cpo car that has the 7 year 1000,000 mile warranty set to expire next month with 93,000 miles on it. I changed my fluid atf about 10,000 miles ago with maxlife atf that valvoline recommends. The transmission is making a whinning noise in park, neutral, drive and reverse. I have had two transmission shops look at the car. One said it was it was the pump which probably has a restricted filter and the other said it sounded like the torque converter was coming apart. My question is am i wasting my time taking it to ford for warranty repair. Valvoline says it will not void my warranty but everything else i read says if it is not licensed with ford then i have voided the warranty.
