A small tolerance issue or a substandard component can be the difference between smooth performance and costly downtime.  At Auto Matic Kings, we know that true quality isn’t just about finding the right part—it’s about knowing exactly how that part was sourced, inspected, and, if necessary, rebuilt to perform like new. That’s why our in-house machine shop is at the heart of what we do. With over two decades of experience working on domestic, imported, late model, and vintage transmissions, our in-house capability gives us a unique advantage: complete control over quality, turnaround time, and customization. Here’s why that matters to you. ## 1. Consistent Quality Control When you outsource machining, you’re placing trust in someone else’s standards. With an in-house shop, our standards are the only ones that matter—and they’re high. Every part we rebuild or modify is measured, tested, and re-tested to meet exact manufacturer specifications or, in many cases, to exceed them. From valve bodies to torque converters, our team applies the same meticulous process to every component. By keeping the work under our own roof, we remove the guesswork, ensuring that what leaves our facility is 100% ready for installation and built to last. ## 2. Faster Turnaround Times When a vehicle is down, time is money, whether you’re running a repair shop or [restoring a vintage model](https://blog.automatickings.com/top-5-transmission-upgrades-every-classic-car-rebuilder-should-consider). Having a full machine shop on-site allows us to process orders quickly without waiting for an outside vendor’s schedule. For common parts, we often have fully rebuilt components ready to ship the same day. For harder-to-find or obsolete parts, our technicians can rebuild or adapt a component in-house, often within 24–48 hours. That means less waiting, less disruption, and more satisfied customers. ## 3. Hard-to-Find Parts? Not a Problem. Some parts are simply not available new—or if they are, they’re prohibitively expensive. This is especially true for certain vintage and import models. At Auto Matic Kings, we’ve built our reputation on tracking down these rare components, and when sourcing alone isn’t enough, our machine shop steps in to make it happen. If a part isn’t available on the open market, [we can rebuild an existing one](https://blog.automatickings.com/benefits-of-choosing-rebuilt-transmission-parts) or fabricate critical components to exact specifications. That’s something most of our competitors simply can’t offer. ## 4. Custom Solutions for Unique Applications Not all transmission jobs are one-size-fits-all. In fleet vehicles, performance builds, or specialized equipment, you may need modifications to achieve the desired performance or durability. Our in-house capabilities allow us to adjust gear ratios, modify housings, and adapt parts for non-standard configurations. This kind of flexibility is invaluable when working on custom restorations, heavy-duty commercial vehicles, or performance upgrades where precision tuning is required. ## 5. Cost-Effective Repairs and Rebuilds Using an in-house machine shop gives you the benefits of speed, quality and efficiency. By controlling the rebuilding process ourselves, we cut down on shipping costs, third-party labor charges, and potential rework due to miscommunication or subpar quality. This means we can pass those savings on to you without cutting corners on the end result. In short, our customers get a better product at a better price. ## 6. The Knowledge Behind the Machines A machine shop is only as good as the people running it. Our team brings decades of combined experience in automatic transmissions, and they understand not just how to machine a part, but how it will perform under real-world conditions. This insight allows us to anticipate potential issues before they become problems and to fine-tune each component for optimal reliability and performance. ## The Auto Matic Kings Difference From domestic to imports, late models to vintage, Auto Matic Kings has been serving the industry for over 20 years with a commitment to quality, service, and expertise that’s second to none. If you need a transmission part—especially the hard-to-find ones—there’s a good chance we have it. And if we don’t? We can likely rebuild or source it within a day or two. Whether you’re working on a late-model daily driver, a high-mileage fleet vehicle, or a vintage classic, our in-house machine shop means we can deliver exactly what you need when you need it. ## Recent Posts Transmission Parts ### [700R4 Pump Assembly: Signs It Needs Replacing](https://blog.automatickings.com/700r4-pump-assembly-signs-it-needs-replacing) Our experts share the warning signs of a failing 700R4 pump assembly, what causes pump damage, and why replacing worn components early can prevent major transmission failure.
