Description

The 66RFE transmission is plagued by many of the same component failures as its bigger sibling, the 68RFE. This includes valve body cross-leaks, a worn SSV bore, and Overdrive (OD) clutch failure. The BD Roadmaster 66RFE transmission addresses these issues with an upgraded valve body, featuring a billet steel-sleeved SSV bore for leak-free, reliable valve operation, and a gasketed separator plate that prevents cross-leaks from robbing OD clutch pressure. Combined with a line pressure booster and a ProForce torque converter, the Roadmaster 66RFE transmission is a reliable upgrade for stock or mildly upgraded 5.7L/6.4L HEMI equipped Ram 2500 and 3500 series trucks.
