Can a 1992 Toyota pickup v6 transmission fit up to a 22R?

No, a 1992 Toyota pickup V6 transmission is not compatible with a 22R engine. The V6 transmission is designed for a different engine configuration and has different mounting points, bellhousing designs, and torque specifications compared to the 22R. If you're looking to swap components, it's essential to use a transmission specifically designed for the 22R engine.
