Prevents torque converter “shudder” and clutch slippage!

It’s strange but true—the torque converter in ’94-’01 Dodge-Cummins applications is more likely to slip at part throttle than full throttle. Why? Because the transmission’s line pressure is controlled by throttle input—the more throttle you give it, the higher the line pressure goes. The problem is, the Cummins produces its peak torque at light throttle, when line pressure is at its lowest! The innovative BD PressureLoc is designed specifically to address this problem. 

The PressureLoc increases converter lock-up clutch apply pressure by 30% at light throttle by rotating the transmission’s throttle shaft to a position that approximates 3/4 throttle. Designed primarily for stock or mildly modified engine applications and for owners who have installed an exhaust brake and would like added protection from slippage. This is not a substitute for a modified valve body! For higher horsepower and/or heavily loaded applications, we recommend the addition of a BD Performance valve body. Call for details.
