PressureLoc Transmission Controls

1995-2001 Ford E4OD & 4R100 Transmissions. The BD PressureLoc plugs in and increases your transmissions hydraulic pressure to hold the clutch plates together to prevent slipping which results in over heating and premature wear.

Stock Ford automatic transmission pressures are not high enough at idle for exhaust brake applications or at light throttle position for stock and modified engine power.

Additional engine performance results in less throttle travel to achieve the same vehicle speed which results in less hydraulic pressure that is holding the clutch plates together. The PressureLoc increases the pressure every time the lock up clutch engages. This increases the pressure applied to all the clutches in the transmission.

Exhaust brakes engage when you have your foot off of the accelerator pedal and this is when transmission pressures are the lowest. When the convertor lock up clutch is engaged 100% of the retarding power can be transferred but the clutch applied pressure should be increased with a PressureLoc.

This new state of the art technology has been designed to easily plug into the transmission. It increases the pressure to a predetermined level rather than a percentage increase over the present level.
