The Toyota Land Cruiser Prado powered by the 4.0L 1GR-FE V6 engine uses robust transmissions designed for towing and off-road capability. Early 120 and 150-series models feature the reliable A750F 5-speed automatic with Super ECT for adaptive shift timing. Later 150-series facelift models upgraded to the AC60F 6-speed automatic, offering improved fuel economy and sequential manual gear control for steep descents. Select markets also offered the rugged RA61F 6-speed manual for maximum driver control and durability.
