BD’s exchange valve bodies are modified, tuned and
tested to provide optimum performance in towing and performance applications.
These units feature increase line pressure, revised manual valve design,  and a custom BD seperator plate. The end
result is improved shift quality, increased clutch holding capacity, and
extended transmission life. What’s more, BD’s Dodge valve bodies allow for
first and second gear lock-up, a great feature for slowing heavy loads down
steep grades (AutoLoc/TorqLoc required). Add longevity and performance to
your transmission, while making your truck fun to drive.
