ABOUT THE PRODUCT

The 66RFE transmission shares many pain points with its 68RFE sibling—valve body cross-leaks, worn SSV (Solenoid Switch Valve) bores, and overdrive (OD) clutch failure that shows up as slip, heat, and early wear. The Monster StreetMonster 66RFE fixes the root causes with an upgraded valve body featuring a billet steel–sleeved SSV bore for tight, leak-free operation and a gasketed separator plate that prevents cross-leaks from bleeding off OD apply pressure. Paired with a Heavy-Duty torque converter, this build delivers cooler temps, firmer apply, and long-term reliability for stock to mildly upgraded HEMI-powered Ram 2500/3500 trucks.
