Yes. Diesel Conversion Specialists® currently offers 15 different Adapter Plates that connect a Ford transmission to a Cummins engine. Modern Ford overdrive automatics are very stout and rated for high torque input making them very conversion-friendly.

Mounting the Cummins engine in your Ford truck with our mounts is actually easier than putting the Cummins engine back in a Dodge truck and faster than putting the Ford engine back into the truck.Read More

No, if you are comfortable running electric fans you can leave the transmission in its current location.

These transmissions work ok behind the Cummins, but the gas versions may have wider spacing in the gear ratios than the diesel versions. If you are planning on high performance upgrades, consider a 6 speed swap- as the Cummins will produce more torque than this transmission is rated for.Read More

We now offer the option of using your Ford ® transmission control module (TCM) to control the transmission for 2003-2007 Ford diesel trucks. Understand that since the 6.0 & 6.4 engines made it's power and torque so much differently than the Cummins ® engine, tuning is necessary. Also necessary are several reproduced or intact Ford signals- so don't attempt this at home without some help.
The latest news is that we now have excellent data logging capabilities that make this option available to anyone using specific years of Cummins engines.

They are rated for 520 ft/lbs of torque.Read More

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.Read More

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.
Some guys say the Ford ZF-5 is a better transmission than the Dodge NV4500 and others say just the opposite. That debate aside; from a conversion standpoint the ZF-5 is better and easier- this article explains why.Read More

Diesel Conversion Specialists works hard to provide high quality, conversion friendly, engines for a reasonable price. In today's market the term "remanufactured engine" can mean different things and often times will leave you on the hunt for new or used parts to complete the engine build. Purchasing a conversion friendly engine ensures you get the right engine for your conversion. We always have a healthy stock of engines and are never more than a few days away from having an engine ready for you. If you require a custom built engine we offer those as well.
Anytime you purchase an engine and conversion kit from DCS we dress the engine with as many conversion parts as possible. Not only does this save you wrench time, if you have your old engine removed, your DCS refit engine will be drop in ready.
We have a rotating stock of engines and often sell them more quickly than we can update the website. Give us a call for pricing and details.
