If you’re in the market for a manual transmission that won’t let you down, the Zumbrota Drivetrain Manual Transmission might just be what you need. These aren’t your run-of-the-mill rebuilds; they go through a thorough three-step inspection process that ensures you’re getting something solid. First off, they kick things off with a pre-inspection to check for any case cracks or excessive wear. It’s a crucial step, especially since many cores come with their own set of OEM-related issues. You don’t want to be surprised down the road, right?

Next, they measure all the component parts to ensure they meet OEM specifications. This isn’t just a quick glance; it’s all about precision. After that, there’s a final post-build inspection to make sure everything is up to the high standards Zumbrota sets. And trust me, they don’t cut corners—everything from gear wear to mainshaft straightness is rigorously checked. They even put the units through a dyno test to simulate real-world scenarios, which is pretty reassuring when you’re about to take your Jeep off-road.

One of the standout features of these transmissions is the attention to cleanliness. They undergo a unique hydro-blast rinse and sandblasting procedure, followed by a proprietary deep cleaning process. It’s all about ensuring that every nook and cranny is spotless, so you can count on smooth operation for miles to come.

And here’s the kicker: all Zumbrota manual transmissions come with a 2-year unlimited mileage warranty. That’s peace of mind you can’t overlook. So if you’re rocking a Jeep Wrangler RWD from 2007 to 2008, this NSG370 6-Speed Manual Transmission is designed specifically for your ride.
