Every transmission is handled by one technician from start to finish.

Each performance transmission is different and each customer has different needs. Allowing a single builder to craft your transmission means that he is intimately involved with both the transmission and the project. He has your requirements in mind at every point in the process.

Choose Your High-Performance Transmissions

At Gearstar Transmissions, we specialize in crafting high-performance automatic and manual transmissions for enthusiasts who demand the best.

The evolution and technical characteristics of automatic transmission systems have been remarkable, with General Motors introducing major models that have set industry standards. These systems have advanced significantly over the decades, utilizing a torque converter to facilitate gear changes without the need for a clutch.

Whether you are looking for a Ford performance transmission, a GM performance transmission, or a Mopar performance transmission – we’ve got you covered.

Every Transmission Assembly is Handled by One Technician from Start to Finish

When you trust Gearstar with your transmission, you’re not just getting a product—you’re getting a personalized experience. Each performance transmission is built by a single master technician who oversees your project from beginning to end. This ensures that every detail is tailored to your specific needs and vehicle requirements.

Using high-quality components, including valve bodies, ensures the best performance and reliability of your transmission system.

Having one technician dedicated to your build guarantees consistency, quality, and a deep understanding of your project. Your transmission is treated like it’s our own, with care and precision at every step, giving you peace of mind knowing your vehicle is in good hands.

We Only Build High-Performance Automatic and Manual Transmissions

At Gearstar, we live and breathe performance. We’re not here to rebuild everyday commuter vehicles—we’re here to power the cars that ignite your passion. Whether you’re driving a Ford, GM, or Mopar, we specialize in creating transmissions that deliver unmatched performance and reliability.

For Ford enthusiasts, we build transmissions that handle the power and performance of Mustangs, F-150s, and other iconic models. GM fans can trust us to deliver transmissions perfect for Camaros, Corvettes, and Chevy trucks. Turbo-Hydramatic models were initially identified by letters followed by a series or version number, but in 1987, GM transitioned to a simpler naming scheme that included a numerical designation indicating the specific model.

Gearstar builds automatic transmissions for Chevrolet vehicles, highlighting models like Camaros and Corvettes. And for Mopar lovers, we design transmissions that bring out the best in Challengers, Chargers, and other Mopar muscle cars.

We understand how much your car means to you, and we treat every build with the respect and attention it deserves.

Types of Transmissions

Automatic Transmissions

Automatic transmissions are designed to automatically change gears without the need for driver input. They use a complex system of sensors, hydraulic pumps, and gearsets to adjust the gear ratio and provide smooth acceleration. Automatic transmissions are popular in modern vehicles due to their ease of use and convenience. They are particularly well-suited for city driving and heavy traffic conditions.

Manual Transmissions

Manual transmissions, on the other hand, require the driver to manually change gears using a clutch pedal and gearshift. They offer more control over the vehicle and are often preferred by driving enthusiasts. Manual transmissions are typically more fuel-efficient and cost-effective than automatic transmissions, but they require more driver input and can be more challenging to use in heavy traffic.

The Best Transmission Parts Make the Best Transmissions

Quality starts with the components we use. At Gearstar, we source only the top US-made parts for our transmissions. From gears and clutches to seals and bearings, every part is selected for its durability and performance.
