If you're in the market for a solid manual transmission that can handle the rigors of off-roading and everyday driving, the Zumbrota Drivetrain Manual Transmission might just be what you need. I've had my hands on one of these, and let me tell you, they don't cut corners. Each unit goes through a rigorous three-step inspection process that ensures you're getting something reliable and built to last.

First off, they kick things off with a pre-inspection to check for any case cracks or wear issues that might be lurking. After that, they measure all the components to make sure they meet OEM specs. This isn’t just a slap-it-together kind of deal; they really pay attention to the details. The final step is all about quality—things like shaft straightness, gear wear, and synchronizers are put through the wringer to ensure they meet OEM standards. Plus, they replace all the seals and even put each unit on a dyno to test operation, shiftability, and noise levels. It’s impressive, to say the least.

One of the standout features is that it's a 5-speed manual transmission designed for 4-wheel drive, perfect for your Dodge W250 or W350 from the early '90s. If you're thinking about doing a G360 to NV4500 conversion, this is the way to go. And don’t worry about any dirty parts; they use a hydro-blast rinse and sandblasting for the internal and external components, followed by a proprietary deep cleaning process. It’s all about getting the grime out so you can hit the trails without a hitch.

Now, for the specs: this bad boy has a fluid capacity of 5 quarts, but you’ll need to grab your own transmission fluid—options include GM 19369226, Redline 50504, or Amsoil MTG. It’s not pre-filled, so just keep that in mind when you’re getting ready to install it.

So if you're driving a Dodge W250 4WD from '90 to '93 or a W350 4WD from '92 to '93, this NV4500 manual transmission is a solid upgrade. It’s built for performance and reliability, and you can feel confident knowing it’s been put together with care and precision.
