About G3
G3 Transmission and Auto is a growing, family- and veteran-owned independent repair shop in Smithville, Missouri.
We are expanding our full-service automotive repair operation while maintaining the transmission and diesel expertise our reputation was built on. We service gas and diesel cars, trucks, SUVs, and work vehicles.
We rebuild transmissions in-house and handle everything from everyday repairs to towing, diesel, and performance applications. We are looking for someone who wants to develop a long-term career in a specialized field while remaining involved in automotive repair.
We are building G3 to be the consumer’s shop—the place people trust with their own vehicles and the vehicles their families drive. That requires honest recommendations, clear documentation, careful workmanship, and repairs we can stand behind.
We are laid-back and enjoy working together, but we take our work, our customers, and the future of the business seriously.
