All About Us

At G3 Transmission, we bring 40 years of professional experience to every transmission repair and rebuild. As a veteran-owned, family-operated shop, we take pride in delivering honest, high-quality workmanship with a commitment to keeping your vehicle running at its best.

​

We specialize in GM, Ford, and Dodge diesel transmissions, but our expertise goes far beyond that. Whether it’s a Hydramatic in a vintage classic or a 10L1000 in a modern towing machine, we have the knowledge and skill to handle it. Unlike many shops that push full replacements at extra cost to the customer, we focus on repairing transmissions whenever possible, saving you money while keeping your vehicle on the road. Our team has the rare ability to diagnose and repair faults in today’s most complex transmissions, including those that many shops won’t touch.

​

At G3 Transmission, we place a heavy focus on perfection in every build. We carefully spec each part, develop precise transmission recipes, and ensure lasting durability with a process built on precision. Every repair and rebuild takes place in a clean, organized, and professional environment, where attention to detail is the foundation of everything we do.

​

Your vehicle is more than just transportation. It’s an investment. That’s why we provide long-lasting, precision-built solutions backed by expert craftsmanship and top-tier customer service. When you choose G3 Transmission, you're choosing a team that values integrity, innovation, and your peace of mind.
