Specifications
The 4R100 transmission is a heavy-duty, electronically controlled, four-speed automatic transmission primarily designed for Ford’s light-duty and medium-duty trucks, such as the Ford Super Duty series. It was introduced in 1999 and used in various models until the mid-2000s. The transmission features a torque converter, overdrive, and lockup capabilities for improved fuel efficiency. The 4R100 is known for its ability to handle high torque, with a maximum torque capacity of around 440 lb-ft, making it suitable for heavy-duty applications, including towing and off-road driving.
