Remanufactured 4L80E Transmissions for Sale | Fraser Engines

The 4L80E transmission is one of GM’s most respected heavy-duty automatic transmissions, commonly found in Chevy Silverado HD, GMC Sierra HD, Suburban, Express vans, Savana vans, commercial trucks, and heavy-duty GM applications. Built for higher torque capacity than the 4L60E, the 4L80E is a preferred choice for towing, hauling, work trucks, fleet vehicles, and performance builds.

Over time, factory 4L80E transmissions can experience issues such as slipping, harsh shifting, worn clutch packs, pump wear, valve body wear, torque converter failure, overheating, and loss of line pressure. Fraser Engines & Transmissions addresses these problem areas with a professional remanufacturing process designed for durability and long-term reliability.

At Fraser Engines, every remanufactured 4L80E transmission is fully disassembled, cleaned, inspected, and rebuilt using new and upgraded internal components. We correct known wear points with recalibrated valve bodies, improved clutch materials, updated bushings, tested pumps, and upgraded torque converter components designed to meet or exceed OEM specifications.

FRASER Advantage™: Our 4L80E transmissions are built for strength, towing power, commercial durability, and real-world performance. Each unit is engineered to handle demanding use while delivering smooth, dependable shifting.

Every Fraser 4L80E transmission is tested for proper hydraulic pressure, shift quality, torque converter operation, and overall performance before shipment. Many builds include a remanufactured torque converter, upgraded clutch packs, valve body corrections, improved lubrication control, and heavy-duty internal upgrades to help prevent repeat failures.

When you choose a 4L80E transmission from Fraser Engines, you receive a zero-mile remanufactured transmission backed by strong warranty coverage, expert fitment support, and a company trusted for drivetrain solutions since 1961.

Whether you need a stock replacement 4L80E transmission, a heavy-duty towing transmission, or a performance-built 4L80E upgrade, Fraser Engines offers reliable transmission solutions built to match your vehicle, workload, and power demands.
