Prevent torque converter shudder and clutch slippage on the 2005 - 2007 Dodge 5.9L with 48RE transmissions by installing the BD 48RE Pressure Controller. Easily plugs inline with factory sealed connectors to the 48RE TTVA motor on the driver's side of the transmission making for a clean installation.
Like its predecessors (47RH/47RE), the 48RE transmission's low mainline pressure at lighter throttle pedal position can cause shudder and slippage. When coupled behind the Common Rail 5.9L Diesel engine with its peak torque at mid-range RPM's , this potential shudder and slippage can be amplified.
When engaged with the rotary switch mounted on the dash, the Pressure Controller has three different levels that can be selected to increase mainline pressure by mimicking higher throttle positions, preventing mid-range convertor shutter and clutch/band slippage.
The BD Pressure Controller is designed to almost eliminate all shuttle shifting with light throttle and as an added feature, this unit slightly holds or delays shifting to prevent lugging and improve transmission function – reduces shift flare and gear hunting.
The BD Pressure Controller 's pressure increase is at its greatest during light throttle positions and ramps towards stock pressures as the pedal gets closer to full throttle when the extra pressure is no longer needed.
With performance modules for the 5.9L Diesel engine, the increase in horsepower tends to make the driver apply less throttle to obtain desired vehicle speeds. In turn, the less APPS Accelerator Pedal Position Sensor applied causes lower mainline transmission pressures to be developed causing potential shudder and slippage. The Pressure Controller compensates for lower APPS Accelerator Pedal Position Sensor and brings the pressure up to a level to protect the transmission and converter.
Compared to some of the competition on the market, the BD 48RE Pressure Controller has higher pressure, more elaborate control and easy factory plug-in installation. Another reason to think BD when looking for your Diesel transmission needs.
