The ATS 3029503104 is a Five Star torque converter for a 1994–2003 7.3 with an E4OD or a 4R100. Stall stays near stock. Torque multiplication is about 2.4 to 1, against about 1.25 to 1 on the factory converter.

The cover is billet, with ATS’s square-flank drive instead of round tabs. The clutch is the Viskus pack, laser-cut plates and their own friction. Roller bearings sit in the high-load spots. The warranty is 5 years or 500,000 miles. ATS wants a billet input shaft, a billet flex plate, and upgraded clutches with this converter. A stock shaft and a stock plate are the parts that break.

It fits 1994–2003 7.3 trucks with an E4OD or 4R100.
