Remanufactured NV4500 Manual Transmission

The Zumbrota Drivetrain RMT4500D-7 is a remanufactured NV4500 manual transmission, meticulously rebuilt to meet or exceed OEM specifications. This transmission is engineered for 1998-2000 Dodge Ram trucks equipped with the 5.9L engine, a 5-speed gearbox, and 4-wheel drive. Constructed with a durable cast iron case and an aluminum top cover, this unit features a 23-spline output shaft and a square four-bolt shift tower. Zumbrota Drivetrain implements a rigorous quality control process, including three distinct inspection stages: a pre-inspection to identify and reject cores with defects like case cracks or excessive wear, a mid-process inspection to ensure all components meet OEM standards, and a final post-build inspection to verify adherence to strict quality benchmarks. Internally, every component receives a 100% inspection, encompassing detailed gear wear checks, mainshaft straightness tests, and synchronizer performance testing. To guarantee optimal performance and reliability, all remanufactured transmissions are subjected to dyno testing, simulating various real-life driving conditions before they are approved for shipment.
