toyota g transmission

Toyota Motor Corporation's G 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 W-series. The G52, G54, G57, and G58 are externally and internally very similar aside from the gear ratios.
