2012 Expedition EL Transmission slip


99K miles and sometimes the transmission will hesitate when I am going slow3-4 mph. I might be pulling out of a parking lot where the exit is slightly downhill, I will take my foot off the gas and then when I slowly add power the trans doesn't catch right away and I can hear and feel it jumping back in "gear"? Sometimes it slams into gear
