Both Jatco and Aisin manufacture excellent, modern technology transmissions. I am always fascinated by the details of the various co-operation agreements between Japanese automotive companies.
Jatco (Japanese Automatic Transmission Company) is an affiliate of Nissan that was created in 1999 by spinning off their automatic transmission/CVT development and production capabilities. As far as I know, Nissan is the majority shareholder, but Mitsubishi also holds a significant number of shares in Jatco.
Mitsubishi did a similar thing by spinning off Diamondmatic (their automatic transmission capability), but this company was promptly acquired by Jatco in 2003. This meant that the Gen 3 Pajero's transmission, that was developed by Mitsubishi, came to be built by Jatco.
Jatco has supplied transmissions to the likes of BMW, VW (Lupo, Polo, Golf, Sharan), Jaguar (X-Type), Land Rover (Freelander), Subaru (Legacy), Mazda (RX-8) and Ford (Mondeo).
Aisin is also an independent company, like Jatco, but with links to Toyota. They produce automatic transmissions, but also many other drivetrain and chassis components. Up to 1996 they supplied Toyota exclusively, but now count Daimler Chrysler, Isuzu, Mazda, Nissan, Mitsubishi, GM, Honda, Porsche, VW, Audi and Hyundai among their clients.
