ZF6- Ford started using this transmission design in ’99 and they work well behind the Cummins. They are rated for 520 ft/lbs of torque. Our adapter plate for this transmission uses the Ford 6.0 starter, so no grinding of the transmission or engine block is required for starter clearance.

It is possible to use the Ford 6.0 single mass clutch with our custom flywheel. Some stock application 6.0’s have a dual mass clutch these will not work. The best option is to use a Ford 7.3 ZF6 clutch with the proper flywheel all of which is included in the complete conversion kits.

If you have a 4-speed manual or 3-speed automatic, swapping in a 5-speed manual is something to seriously consider. The earlier transmissions were tough, but they simply were not designed for the torque the Cummins engines produce. Their input shafts are smaller, the clutches are smaller, and without an overdrive you will lose all reasonable fuel economy at highway speeds due to running the engine at such high RPM's.
