Cummins® to Ford® 7.3 Power Stroke® ZF 6-Speed
Posted by Diesel Conversion Specialists® on Oct 15th 2020
The 1999-2003 Ford® 7.3 Diesel 6-speed works well behind a Cummins® engine. Ford started using this transmission in 1999. If your truck did not have one of these transmissions originally, you may want to consider swapping one in especially if you are planning to use your truck for heavy trailer pulling. They are rated for 650 ft/lbs of torque.
The Diesel Conversion Specialists® adapter plate for this transmission uses a 2003 - 2007 Ford 6.0L diesel starter, depending on the adapter plate you order. Grinding the bell housing starter pocket is required to give necessary starter to transmission clearance.
The Adapter Plate includes instructions, bolts and crankshaft spacer. Dodge® Cummins 6 speed flywheel and South Bend clutch kit can be purchased seperatly.
