W58 Transmission

The W58 transmission represents Aisin’s commitment to producing versatile manual gearboxes that serve both passenger car and light truck applications with equal competence. This 5-speed unit handles approximately 250 lb-ft of torque, making it suitable for naturally aspirated inline-six engines and moderate V6 powerplants found across Toyota’s rear-wheel-drive lineup. Manufactured from 1983 through 2002, the W58 served Toyota Supra (non-turbo), Cressida, pickup trucks, and 4Runner models requiring reliable manual transmission configurations. The gearbox features a 0.78:1 overdrive ratio in fifth gear that provides comfortable highway cruising while maintaining strong acceleration through lower gear ranges. Internal components include triple-cone synchronizers on first and second gears, needle roller bearings throughout, and heat-treated steel gears machined for quiet operation and extended service life.

The aluminum case design incorporates ribbing patterns that enhance rigidity while minimizing overall weight compared to cast-iron alternatives. Compatible with Toyota’s R-series inline-six and 3VZ V6 engines, this transmission integrates seamlessly with factory clutch systems and driveline components.
