At RG Diesel, LLC , we specialize in high-performance diesel transmissions. It’s not all about the engine; a high-performance diesel truck with a well-maintained transmission has the ability to crush the competition right out of the gate by effectively putting massive torque to the ground. Avoid catastrophic transmission failures by getting the expert mechanics at RG Diesel, LLC to install your performance upgrades like a C eliminator kit, high-torque converter, or extra strong, bulletproof flexplate.

At RG Diesel, LLC, we make auto repair easy. Replace your standard clutch with a clutch designed to provide higher torque and preload for lightning-fast, torque-sensing traction when you need it most. A diesel truck’s transmission carries the engine’s power to the drive axles, and without it, your vehicle simply will not run. Don’t get sidelined because of a transmission problem. Bring your high-performance diesel vehicle to RG Diesel, LLC in Greeneville at 3460 W Andrew Johnson Hwy or call today to set up an appointment at 423-823-9987.
