It’s a basic principle of automatic transmissions: More throttle input results in higher transmission line pressure to keep the clutch plates engaged. The problem is, once the Power Stroke engine is modified, it produces more power and torque with less throttle input, which means the engine may be producing peak torque when line pressure is still low. The result can be clutch slippage, increased heat, and accelerated wear.

The BD PressureLoc for 1995-2003 Ford E40D and 4R100 transmissions simply plugs in to the transmission and increases line pressure to hold the clutch plates together at peak torque. The PressureLoc increases the pressure every time the lock up clutch engages, increasing pressure to both the clutches.
 
The PressureLoc is particularly useful in exhaust brake applications, as exhaust brakes engage when the throttle is released, and line pressure is at its lowest. With PressureLoc, maximum pressure is applied to the transmission, allowing you to utilize 100% of the exhaust brake’s retarding power.

Reduced slippage. Greater control. You can’t afford not to have the PressureLoc on your Ford transmission! Call and order yours today!
