BD Diesel 2011–2014 Ford 6.7L 6R140 Stage 4 Transmission and Converter Package
The BD Diesel Stage 4 Transmission and Converter Package stands out as the direct solution for 2011–2014 Ford 6.7L Power Stroke owners facing stock transmission failures under high torque loads from tuning or heavy towing. This complete assembly addresses common weak points in the 6R140 transmission by incorporating upgraded clutches, valve body modifications, and a high-stall torque converter that deliver reliable power transfer up to 650 HP and 1,400 lb-ft of torque. Built with reinforced components tested on the dyno for seamless integration, it ensures smooth shifts, reduced heat buildup, and extended service life compared to stock or partial rebuild options. The package includes a deep aluminum pan for added fluid capacity and cooling, plus a pressure controller that boosts line pressure to 300 PSI for firm clutch engagement without slippage. For diesel enthusiasts demanding consistent performance in daily driving, towing up to 20,000 lbs, or track runs, this BD Diesel package provides the full drivetrain reinforcement needed to match modified engine output.
Key Features
- Reinforced Transmission Core: Upgraded forward and direct clutch packs with additional frictions and steels for handling increased torque without wear.
- Modified Valve Body: Enhanced with billet components and recalibrated solenoids for quicker, firmer shifts and improved fluid flow.
- ProForce Torque Converter: Billet multi-disc lockup with increased stall speed for better low-end response and lockup at highway speeds.
- Deep Aluminum Transmission Pan: Adds 4 quarts of fluid capacity with heat-dissipating fins to lower operating temperatures by up to 20°F.
- Pressure Controller: Electronically adjusts line pressure up to 300 PSI to prevent clutch slip and extend component life.
- Dyno-Tested Assembly: Matched transmission and converter validated for peak efficiency and durability under load.
Product Notes
- Requires Ford scan tool to update TCM solenoid codes and perform adaptive relearn procedure post-installation.
- Compatible with both 2WD and 4WD configurations; transfer yoke and rear mount from stock unit during install for 2WD.
- Early 2011 models (pre-January 2012 build) need 6-bolt flexplate upgrade (BD part #1041245 recommended).
- Not compatible with PTO-equipped trucks contact BD for custom options.
Warranty: 36 months/150,000 miles on parts; 12 months/24,000 miles on labor.
Installation Notes
- Professional installation advised due to complexity; transmission fluid flush and cooler line inspection recommended.
- Transfer cooling lines, sensors, and wiring harness from original transmission.
- Verify flexplate bolt pattern matches (6-bolt for post-2011; upgrade if needed).
- After install, drive cycle required for TCM adaptation; monitor fluid levels and temperatures.
