2026 Billet 6R140 Transmission – Warren Diesel Shop
The Billet 6R140 is the flagship high-performance rebuild of the Ford TorqShift 6R140 automatic transmission for 2011-2019 Ford Super Duty trucks with the 6.7L Powerstroke diesel. Warrantied to 1000+ rear-wheel horsepower (RWHP), it’s engineered for extreme tuned builds, drag racing, sled pulling, heavy hauling, or ultimate street power—delivering unbreakable strength with excellent drivability.
Hand-assembled with elite components from Goerend, TCS, Ford, Exedy, and TransTec, this top-tier build includes a TCS billet intermediate shaft and stroked 10-pack overdrive drum (disassembled, shimmed for clearance, and precision-welded) for maximum torque capacity and reduced heat.
10-Pack Stroked Overdrive Drum for Ford 6R140 – Warren Diesel Shop
The stroked 10-pack overdrive drum is a precision-modified OEM Ford component designed for extreme-performance 6R140 transmissions in 2011-2019 6.7L Powerstroke trucks. To accommodate 10 high-energy clutches (vs. stock 7), the drum is carefully disassembled, shimmed for additional clearance, and the halves are TIG-welded back together with expert craftsmanship for perfect alignment and strength.
This modification dramatically increases holding power in the critical 4-5-6 (overdrive) clutch pack, eliminating shift flare, reducing heat, and supporting 1000+ RWHP builds for competition, sled pulling, or aggressive street use.
