Aisin transmissions are widely utilized across a massive spectrum of global automotive brands due to the company's status as a premier tier-one supplier. Because Aisin is closely affiliated with the Toyota Group, vehicles built by Toyota, Lexus, and Scion extensively feature Aisin automatic, manual, and continuously variable transmissions. Additionally, numerous other international automotive giants—including Volvo, General Motors, Mazda, Porsche, Volkswagen, Audi, Jeep, and Hyundai—frequently integrate Aisin transmissions into various models of their cars, SUVs, and trucks to optimize fuel efficiency and mechanical reliability.
