NV4500 5-Speed Manual Transmission

The Zumbrota Drivetrain RMT4500D-9 is a fully remanufactured NV4500 5-speed manual transmission engineered for 2003-2004 Dodge Ram trucks equipped with the 8.0L or diesel engines. This transmission is built to exacting quality standards, incorporating a rigorous three-step inspection process. This includes a pre-inspection to identify case cracks, excessive wear, and OEM-specific issues, followed by measurement of component parts to ensure they meet OEM specifications. The final step guarantees each unit is built to Zumbrota's strict quality standards, with thorough testing of shaft straightness, gear wear, and synchronizers. Every transmission undergoes extensive testing, including seal replacement and dyno-testing for operation, shiftability, and noise levels. Zumbrota also employs a unique cleaning procedure involving hydro-blast rinsing and sandblasting for internal and external parts, followed by a proprietary shot-peening deep clean, setting a high standard for manual transmission remanufacturing.
