Ready to upgrade your 6R80? PBH has everything you need to build a transmission that’s ready for the street, the strip — or both. Whether you’re doing a fresh rebuild or chasing high-horsepower durability, this kit is built with the same industry-leading components trusted by racers and builders nationwide.

It all starts with our base rebuild kit, featuring GPZ high-performance frictions and steels, a billet 300M intermediate shaft, new seals, and a fresh filter. From there, you can tailor your setup with proven upgrades like a reinforced forward planetary, heavy-duty center support, billet main shaft, and upgraded one-way clutch — all designed to handle serious power and hard launches.
