Is your performance module causing transmission shudder and clutch slippage? Probably is...
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 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 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
