Trans slips in high gear

Hey Guys and Gals,I bought a 2009 Flex with 101,000 miles on it and have put on another 12,000 . I love this car. About two weeks ago while cruising at about 60 mph and at about 1,800 rpm I started up a grade and when I started to compensate by slowly adding some gas the trans started to jerk a little. It has started to do it now on a flat road way. But only in high gear. Any ideas on what might be the problem? I might ad that I live in Loreto, Baja California Sur. No Ford shop around. Thank you in advance for the help.

Well it turns out that the transmission wasn't slipping at all. The engine was misfiring when under a load at low RPM.There was a small hole in the insulator of one the spark plugs that caused the spark plug to ground out to the block.It was more noticeable in overdrive. Everything's good again.
