6-Speed Manual Transmission

The Zumbrota RMTM12C-1 is a remanufactured 6-speed manual transmission specifically engineered for GM 2001-2004 Corvette models, including those equipped with the LS6 and Z06 packages. This transmission undergoes a meticulous three-step inspection process to ensure the highest quality and reliability. The remanufacturing process includes a pre-inspection for case cracks and wear, measurement of component parts to meet OEM specifications, and a final build inspection to guarantee adherence to strict standards. During the remanufacturing, Zumbrota Drivetrain performs comprehensive checks on internal components, including shaft straightness, gear wear, and synchronizers. All seals are replaced, and each unit is subjected to dyno testing to verify operation, shiftability, and noise levels. Additionally, an exclusive hydro-blast rinse and sandblasting procedure, followed by proprietary shot-enticed deep cleaning, ensures a superior level of cleanliness and preparation for the transmission's internal and external parts. All transmissions are dyno-tested through numerous real-life scenarios to confirm performance and durability before they are shipped. This rigorous testing and quality control process sets a high standard for manual transmission remanufacturing, providing a precise and reliable unit for your Corvette.
