The BD Diesel 48RE transmission kit for 2004.5–2007 Dodge 2WD with TVV stepper motor upgrades internal components for greater durability. It uses rollerized thrust bearings, a new valve body, drilled lubrication passages and heavier clutch packs, while the rigid aluminum pan adds oil capacity and cooling fins. Increased clutch apply pressures and upgraded governor components help firmer shifts and extended drivetrain life.
