The Ford Ranger has long been a favorite among compact and midsize pickup truck enthusiasts. Known for its rugged reliability, the Ranger’s transmission system plays a critical role in its on-road and off-road performance. Whether you're driving an older model or a modern turbocharged Ranger, understanding the transmission is essential to keeping it running smoothly.
