How do you change a gearbox in a rav4?

To change a gearbox in a RAV4, first ensure the vehicle is safely elevated and supported. Disconnect the battery, then drain the Transmission Fluid and remove any components obstructing access to the gearbox, such as the drive shafts and exhaust. Unbolt the gearbox from the engine, carefully detach it, and replace it with the new unit, reassembling in the reverse order.
