GMC 4L80e Transmission

A complete,  GMC heavy-duty 4WD drivetrain package featuring a low-mileage 4L80E 4-speed automatic overdrive transmission bolted directly to its matching 4×4 transfer case. Pulled from a well-maintained donor vehicle with only 20,000 original miles, this assembly has been fully cleaned, inspected, fluid-tested, and verified to deliver flawless factory performance under load. Perfect for high-horsepower LS swaps, turbo truck builds, or upgrading a weaker 4L60E setup, this ultra-reliable 4×4 transmission combo comes complete with the torque converter and is backed by a rock-solid, peace-of-mind 2-year warranty.
