BD Diesel Valve Body - 1991-1993 Dodge 518

The transmission valve body is the brain of your automatic transmission, directing hydraulic fluid to engage clutches and bands for shifting. For your 1991-1993 Dodge D250, D350, or W250 equipped with the 518 transmission, this modified valve body from BD Diesel is built to handle more demanding use, whether you're towing heavy loads or just want a more responsive feel.

BD Diesel takes a comprehensive approach, modifying, tuning, and testing each valve body to ensure it performs optimally. They've incorporated increased mainline pressure with new trim valves and hand-lapped surfaces to prevent internal leaks, which directly translates to increased clutch holding capacity and improved shift quality. This means smoother gear changes and a transmission that can handle more torque without slipping. The design also includes anti-shuttle technology and larger oil ports for better fluid flow, contributing to reduced friction and extended transmission life. A notable feature is the revised manual valve design, which allows for first and second gear lock-up when used with BD's AutoLoc/TorqLoc systems, providing valuable engine braking on steep descents.

This valve body is a solid option for adding both longevity and performance to your truck's drivetrain, making it more enjoyable to drive, especially when under load. The package includes the modified valve body and necessary hardware for installation. Remember to consult your service manual for specific installation procedures and torque specifications.
