Dodge Cummins (1991-2007) 47RH, 12/24-valve 47RE, 47RE
Transmission Shift Strategy Modifications
BD’s exchange valve bodies are modified, tuned and tested to provide optimum performance in towing and performance applications. These units feature revised valve design, new springs, larger oil ports and proprietary governor piston dimensions. Hand lapped surfaces prevent internal leakage, while new trim valves increase mainline pressure. The end result is improved shift quality, increased clutch holding capacity, reduced friction 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 heaving loads down steep grades (TowLoc/TorqLoc required) Add longevity and performance to your transmission, while making your truck fun to drive.
An economical way to improve the performance and clutch life of your stock transmission is to install a BD Performance Valve Body. Our complete upgrade of the stock valve body consists of new valve designs, increased capacity springs, revised oil circuits and optimized governor piston dimensions which the improved oil flow reduces temperatures and lowers torque converter evacuation time for quicker clutch apply.
BD’s NEW DESIGN achieves up to 80% higher clutch apply pressures over the stock unit and up to 50% over the competitors with the increase starting at much lower engine rpm’s and at lighter throttle pedal position movement. Light throttle shift firmness is also maintained at these higher apply pressures.
This new building process also eliminates the often referred to “Shuttle Shifting” or hunting-for-gears in the 2004-2006 48RE transmissions.
With the new designed valve bodies achieving the higher pressures, a BD PressureLoc is no longer needed when an exhaust brake is installed to assist in preventing converter lock up clutch slippage – this unit does it all!
We also added second gear lock-up capability that with the addition of one of our TorqLoc or TowLoc kits can offer serious engine retarding capability on towing applications.
Each valve body is tested to ensure proper function before shipping. While you’re replacing the valve body, add one of our heavy duty aluminum oil pans for greater oil capacity, cooler oil temperature and improved case rigidity.
