If you're looking to breathe new life into your classic ride, the Zumbrota Drivetrain Manual Transmission is where it's at. These aren't just any rebuilt transmissions; they're crafted with serious attention to detail. Each unit goes through a three-step inspection process that ensures you're getting something reliable and ready to hit the road.

First up, we kick things off with a pre-inspection. This checks for any case cracks, excessive wear, and those pesky OEM issues that can crop up with older cores. Nobody wants to drop a new transmission in only to find out it’s got hidden problems. Next, we measure all the component parts to make sure they meet OEM specs. If something doesn’t pass muster, it doesn’t make it into the final product. Finally, after everything is assembled, we do a post-build inspection to ensure it all meets our strict quality standards.

And let’s talk about the internals. We’re not just giving them a quick once-over; we’re diving deep. Every internal part is inspected—gear wear, mainshaft straightness, synchronizers—you name it. We even dyno-test each unit to simulate real-life driving conditions. You’ll know it’s going to shift smoothly and quietly before you even install it.

But we don’t stop there. Each transmission gets a hydro-blast rinse and sandblasting for both internal and external parts, followed by a proprietary deep cleaning process. It’s a bit of a spa day for your transmission, ensuring it’s as clean and precise as it can be. Plus, you get peace of mind with a 2-year unlimited mileage warranty. That’s how confident we are in our work.

• Three rigorous inspections throughout the remanufacturing process.
• Initial pre-inspection to catch any case cracks or excessive wear.
• Second inspection during the rebuild to ensure all parts meet OEM specifications.
• Final inspection to confirm everything is built to our high standards.
• 100% inspection of internal components, including gear wear and synchronizer testing.
• Dyno-tested to ensure smooth operation in real-world scenarios.
