2026 Performance 4R100 / E4OD Transmission – 500 RWHP
Built for the 7.3L Powerstroke (1995–2003) Rated up to 500 Rear Wheel Horsepower
The 2026 Performance 4R100/E4OD is the perfect upgrade for owners who want significantly more strength than a stock or basic rebuild, without stepping into full-race territory. Ideal for daily driving, heavy towing, and mildly modified 7.3L Powerstrokes running tunes, hybrid injectors, or upgraded turbos.
This transmission delivers reliable, smooth performance on the street while giving you the extra capacity needed for serious towing and added horsepower.
