So when driving my 2016 XLT 3.5L Ecoboost when I do a California stop or slow down almost to a stop then accelerate I notice the gears go from 3rd to 1st then to 2nd when I accelerate, but sometimes it feels real sluggish on acceleration when I do this. I dont notice it in Sport mode havent really tired in tow/haul mode. Any advice on this?? Thanks..
