6-speed 6R80 SelectShift intelligent manumatic gearbox with manual shift mode. Expedition also features a new electric power servo-assisted steering and Pull-Drift Compensation (PDC) which detects crosswinds and compensates for it. The interior remained similar to the outgoing models, but with upgraded materials and a revised prominent center stack, now derived from the 2013-2014 F-150 rather than the 2008-2010 Super Duty. Also new is the latest version of the 8-inch MyFord Touch touchscreen infotainment and telematics system. Push-to-start engine ignition with intelligent access was added and the four-wheel drive mode selector (for models with 4x4) was revised and repositioned. The TowCommand paddle controls were repositioned over the four-wheel drive mode selector, to make way for revised audio and climate controls on the center stack. The new features for 2015 included an optional, revised four-wheel independent suspension system with intelligent continuously controlled damping (CCD) system that alters suspension settings constantly based on 46 parameters and offers comfort, normal, and sport modes. Expedition is the first Ford vehicle in North America to have continuously controlled damping. Other new optional features includes blind-spot information system (BLIS) with cross-traffic alert, and a rearview camera and apps for the infotainment system to help with towing and off-road driving, all of which is standard in the Platinum trim, whose seating and interior features include Brunello leather, a red wine color with tuxedo-stripe accents and French seamed stitching, or black leather with Agate Gray accents.

FTA gives off-road orientation/geometry, 4x4 system status, and traction control system status in real-time. The four-wheel electronic traction control system (brake differential locking control) was recalibrated to take into account the new EcoBoost V6's higher torque output and earlier torque delivery.
