At Procar Northwest Inc. in Redmond, WA, we service all types of transmissions, on any car, truck, or SUV. This includes both All-Wheel Drive and Four-Wheel Drive vehicles, but you may be wondering...what’s the difference? Both types of vehicle supply power to all four wheels, so why use two different terms? Due to the increasing demand for AWD and 4WD vehicles over the last decade, equipped on everything from sports cars to pickup trucks, more and more people are asking these same questions.
