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 convertor lock up clutch slippage – this unit does it all!
(BD still recommends the use of a PressureLoc for transmissions not equipped with one of our new designed valve bodies when an exhaust brake is installed.)
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.

This thing worked awesome for me. I have an 04.5 ram with the TV cable witch makes the trans the 03-04 model. My problem was that the trans couldn't pick a gear under lite throttle, even sometimes just going around a corner, it would shift up, then back down. I did all the recommended stuff that i found online. (new Pressure sensor, New big borg warner solenoid, bands adjusted, TV cable adjusted) Nothing changed. Then i put in a "Brand Name" tow kit, billet accumulator and billet front piston. After all that, it still did the same thing, just harder. This was my last option that i could do myself. I have been in transmissions before, this is no big deal, if you can follow a few instructions, any good mechanic can do this. The instructions are good with pictures. As soon as i left the drive way, i could tell it was better. I have had it in for about 1000 miles now, and this thing works great. No more hunting for gears, it make my truck feel a lot snappier in city driving, i think that is because it is always in the correct gear. Better MPG in town. If you are having the issues i had, just do it. I have no regrets, I just wish that dodge would have build it like this from the factory. Thank you very much BD and Xtream.
