Built to Handle Power Without Backing Down

If your 6.7L Powerstroke build is making serious power, the stock 6R140 transmission just won’t cut it for long. That’s where the Randy's Transmission Stage 2 Crate Transmission comes in. Built to support up to 800 horsepower, this transmission is purpose-built for 2011 to 2019 Ford F250 and F350 Super Duty trucks. It comes packed with premium internal upgrades, including a quad disc billet torque converter, a billet overdrive piston with high return springs, and Raybestos or ALTO G3 clutch components. This setup isn't just for racing or dyno pulls—it’s designed for real-world use where heavy loads, long hauls, and hard launches are part of the daily routine.

Smart Upgrades Inside and Out

Randy’s doesn’t just rebuild a factory transmission—they rethink it from the inside out. This Stage 2 unit features a brand new OE valve body modified for improved oil flow, helping it shift smoothly under pressure. The HD cast aluminum deep pan helps keep temps under control, while fresh gaskets and seals ensure long-term reliability. A new filter is already included, and flexplates can be added depending on inventory and build preferences. Whether you’re towing through the mountains, pushing high boost on the track, or just want a transmission that can grow with your build, this crate unit delivers performance and peace of mind in one well-engineered package. Keep in mind a $500 shipping surcharge applies, but what you get in return is built to last.
