The 2026 Competition 5R110w Transmission by Warren Diesel Shop
 A premium, hand-built performance rebuild engineered exclusively for 2003-2007 Ford Powerstroke 6.0L trucks (with options available for 2008-2010 models). Warrantied to handle up to 600 RWHP, this transmission delivers 50% more power to the ground while being 200% stronger than the factory unit—making it the ideal upgrade for tuned setups focused on street performance, heavy towing, reliable daily driving, or spirited pulls.
At the core is the proven Goerend BF triple disc billet torque converter with billet stator—offering unmatched lockup efficiency, superior heat dissipation, and exceptional torque capacity under heavy loads. It pairs with a durable Goerend billet input shaft to prevent twisting or failure, a Warren Diesel billet pump for optimized fluid pressure and flow, and a welded coast clutch drum designed for maximum durability in demanding conditions.
The build features top-tier re-engineering throughout every critical pack: overdrive (5-pack with piston), intermediate (5-pack), Xtreme direct (6-pack with 1-piece bushing), forward (5-pack), and low/reverse (6-pack). It also includes a machined center support for added stability, an upgraded performance valve body loaded with Sonnax components—including the Teflon manual valve, o-ringed pressure switch plug kit, and low/reverse retaining ring—plus an updated rear hub.
This comprehensive package addresses the factory 5R110w’s common weak points head-on, fixing the weak 3-5 failure, and providing crisp shifts, exceptional holding power, and long-term reliability for trucks with upgraded injectors, turbos, and tunes.
