Remanufactured 6L80 & 6L80E Transmissions for Sale | Fraser Engines

The 6L80 and 6L80E transmissions are widely used 6-speed automatic transmissions found in many GM trucks, SUVs, and performance vehicles. Common applications include the Chevy Silverado, GMC Sierra, Tahoe, Suburban, Yukon, Escalade, Camaro, and Corvette. Known for smooth shifting, improved fuel efficiency, and strong highway performance, the 6L80E is a popular choice for daily driving, towing, hauling, and performance applications.

Over time, factory 6L80E transmissions can experience issues such as torque converter failure, slipping, harsh shifting, clutch wear, pump wear, valve body problems, overheating, and internal fluid contamination. That’s where Fraser Engines & Transmissions sets the standard.

At Fraser Engines, every remanufactured 6L80E transmission is completely disassembled, cleaned, inspected, and rebuilt with new and upgraded internal components. We correct known failure points using updated torque converter components, recalibrated valve bodies, improved clutch materials, upgraded seals, and precision-tested hydraulic systems designed to outperform factory expectations.

FRASER Advantage™: Our 6L80E transmissions are engineered for durability, smooth shift quality, improved torque converter reliability, and real-world performance—whether you're replacing a failed unit or upgrading for towing, hauling, or high-demand driving.

Each unit is tested under real-world driving conditions to verify proper shift timing, line pressure, converter operation, and overall performance before shipment. Many Fraser 6L80E builds include remanufactured torque converters, upgraded clutch packs, valve body corrections, and improved internal sealing—giving you a transmission built for dependable long-term use.

When you choose a 6L80E transmission from Fraser Engines, you’re getting a zero-mile remanufactured transmission backed by strong warranty coverage, expert support, and a company that has been supplying drivetrain solutions since 1961.

Whether you need a stock replacement 6L80E transmission or a heavy-duty upgraded 6L80 transmission, Fraser Engines offers reliable build options to match your vehicle, driving style, and power demands—ensuring the right fit the first time.
