This remanufactured transmission undergoes a rigorous three-step inspection process, ensuring that each unit meets or exceeds OEM specifications.

Quality Assurance Process

The remanufacturing process includes:

• Pre-Inspection: Each unit is thoroughly examined for case cracks, excessive wear, and other OEM-related issues.
• Component Measurement: All internal parts are measured to confirm they meet OEM specifications.
• Final Inspection: A comprehensive post-build inspection verifies that the transmission adheres to Zumbrota's stringent quality standards.

Performance Testing

Every RMT4500C-11 is subjected to extensive testing, including:

• Gear wear assessments and mainshaft straightness tests.
• Synchronizer functionality checks.
• Dynamometer testing to simulate real-world conditions, ensuring smooth operation and shiftability.

Cleaning and Preparation

To maintain the highest standards of cleanliness and performance, Zumbrota employs a unique hydro-blast rinse and sandblasting procedure for both internal and external components. This is followed by a proprietary deep cleaning process that guarantees all contaminants are removed, setting a benchmark in manual transmission remanufacturing.
