Description
The 66RFE transmission is a 6-speed automatic gearbox introduced by Chrysler for use in Ram 2500 and 3500 trucks. Built to handle the demands of heavy-duty gasoline-powered applications, it bridges the gap between light-duty and commercial-grade transmissions. Featuring a cast aluminum case, advanced hydraulic controls, and a three-coplanar planetary gearset system, the 66RFE transmission provides six forward gears and one reverse, with optimized gear ratios for power delivery and fuel efficiency.
Capable of handling up to 660 lb-ft of torque, the 66RFE is well-suited for towing, hauling, and commercial-grade usage. It uses adaptive electronic shift control, a multi-disc clutch pack design, and a lock-up torque converter to ensure smooth transitions and improved drivability. The transmission also includes features such as electronically modulated line pressure, dual filters for improved fluid cleanliness, and compatibility with ATF+4 fluid for enhanced thermal stability.
66RFE fitment requires matching your specific Ram 1500 model year and drivetrain configuration. The 4WD Ram requires the correct output shaft configuration for the transfer case. Our VIN verification confirms the exact 66RFE for your vehicle before it ships.
Ram 1500 V6 owners comparing a used transmission, a remanufactured transmission, and an OEM transmission for the 66RFE will find the used OEM route most practical. A used Dodge 66RFE transmission from a verified low-mileage Ram gives you the factory six-speed Chrysler OEM transmission — the factory Pentastar V6 shift calibration, the factory tow-haul programming — as an OEM transmission at a price that makes the repair sensible. Unlike a remanufactured transmission from a rebuilt core, this is an original factory unit. Choosing a used 66RFE OEM transmission restores the smooth, efficient shifting your Ram was built to deliver.
Every used Dodge 66RFE transmission ships with up to a 90-day warranty and arrives within 2 to 5 business days. Installation is not included. These are genuine Chrysler OEM units, and we stand behind every one.
