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.
