Toyota W Transmission
Toyota Motor Corporation's W family is a family of RWD/4WD transmissions built by Aisin Warner. Physically, these transmissions have much in common (like the bellhousing-to-body bolt pattern) with other Aisin-built transmissions, like the Jeep AX-5 and the Toyota G-series. The W55, W56, W57, W58, and W59 are externally and internally very similar aside from the gear ratios.
