FORD | 6.0L POWERSTROKE 03-07 | TRANSMISSION

The 6.0L Power Stroke can be a very capable truck, but transmission support becomes more important as the miles add up and the workload increases. Slipping, converter issues, heat, and worn internal parts all change how the truck feels on the road and under load. Some trucks need a straightforward rebuild path. Others need stronger hard parts and a better converter so the transmission can hold up the way a diesel work truck should.

That is where BD brings value. We do not treat the 5R110 like a one-size-fits-all transmission. We look at how the truck is used. A daily driver does not always need the same solution as a tow rig, a service truck, or a 6.0L that has been pushed beyond stock. Some owners want to rebuild their own transmission with proven parts. Others want a complete matched package that takes the guesswork out of the job. This collection is built around those real-world decisions.

Built around the transmission paths owners actually need

• Torque converter upgrades for better holding power and stronger towing performance
• Build-It kits for owners rebuilding a 5R110 with the right parts for the job
• Matched transmission and converter packages for a more complete solution
• Flexplate upgrades for stronger support where it matters
• Cooling solutions for trucks that need better transmission temperature control
