The difference between consistent daily performance and unplanned mechanical failures can be determined by the state of the Ford F-150 transmission. From the base V6 to the potent turbocharged EcoBoost engines, Ford built this transmission system to support a variety of engines and configurations. A smooth shift from low-end torque to high-speed cruising is necessary for these pairings. Performance can be severely hampered by worn-out parts, low transmission fluid, or overheating. Because of this, it is advised to routinely flush the Ford F-150 transmission fluid and make sure that all associated parts, such as the torque converter and gearbox cooler, are operating as intended.
