Upgrade your Lexus RX300 with this clean, low-mileage JDM Automatic Transmission — a direct-fit replacement for the 1999–2003 Lexus RX300 AWD 3.0L V6 models. Imported directly from Japan by J-Spec Auto Sports Inc., this automatic transmission has been thoroughly inspected and compression tested for performance and reliability. It’s the perfect solution for drivers seeking a reliable, cost-effective replacement transmission to get back on the road quickly and confidently.

This AWD automatic transmission is mated to the 3.0L 1MZ-FE V6 engine found in the RX300 platform. The JDM variant typically features lower mileage than its North American counterparts and is known for smoother shifting and longer lifespan due to Japan’s stricter vehicle mileage regulations and maintenance standards.
