The Ford E4OD and 4R100: Powerstroke's Heavy-Duty Transmission Legacy

The Ford E4OD (Electronic 4-Speed Overdrive) and its evolutionary successor, the 4R100, represent Ford's commitment to heavy-duty automatic transmission technology. These transmissions, particularly notable in Powerstroke diesel applications, set the standard for durability in the heavy-duty pickup segment.

Whether building for commercial use, competition, or heavy towing, our expertise ensures each transmission is properly matched to its intended use. We address known weaknesses while enhancing the transmission's inherent strengths, resulting in a reliable, high-performance unit capable of exceeding OEM specifications.

The E4OD/4R100 platform continues to be popular for:
• Powerstroke builds
• Heavy towing applications
• Commercial service
• Competition use
• Fleet applications
