If you’re looking for a manual transmission that’s been rebuilt with care and precision, the Zumbrota Drivetrain Manual Transmission is a solid choice. These units go through a rigorous three-step inspection process that really sets them apart from the rest. First off, we kick things off with a pre-inspection to check for any case cracks or wear that could cause headaches down the road. If a core has OEM-related issues, we catch them right here before moving forward.

Next up, we dive deep into the nitty-gritty. Every component is measured to ensure it meets OEM specifications. We’re talking about checking shaft straightness, gear wear, and synchronizer performance. It’s all about making sure each part is up to snuff. After that, we put the finishing touches on with a final inspection to guarantee that the unit is built to our strict standards.

But we don’t just stop there. Every transmission is dyno-tested under real-world conditions to make sure it shifts smoothly and operates quietly. We replace seals and run each unit through a hydro-blast rinse and sandblasting procedure to clean both internal and external parts thoroughly. This isn’t just a quick polish; it’s a full-on deep clean that ensures reliability at every critical touchpoint.

And let’s not forget about the warranty. We back our work with a 2-year unlimited mileage warranty, so you can hit the road with confidence.
