You may be able to utilize our custom carrier bearing mount, which may make it possible to use your drive shafts as they are with an engine driven fan. The engine mounts are an excellent design with a bolt going all the way through the isolator, instead of relying on rubber and weak interlocking tabs to secure them to the frame cross member. Because the Cummins engines are longer this will move your transmission back 2” to 3” causing you to move your transmission cross member back. ENGINE MOUNTS Our motor mounts are pre-drilled to accommodate for the stock engine fan (recommended). They are precision machined from aircraft grade (6061) aluminum. Our adapter plate replaces the adapter already on the back of the Cummins engine, making a factory quality connection for the transmission. The adapter plate is sold with the required custom flexplate. Two holes in the top of the adapter are not used (the 4R100 does not have these holes and two in the bottom are not used either) or if you want to use them drilling out the threads in the bottom holes in the transmission is required. It is actually the same adapter that was designed for the 6.0L 5R110 automatic transmission but it also works for the 4R100, and allows you to upgrade to the 5R110 in the future if you'd like. These are very good transmissions for the conversion, and worth the time swapping in if you want a manual trans INFORMATION ON PARTS IN OUR KITS ADAPTER PLATE Our adapter plate kit uses the 6.0L Ford Power Stroke starter. We make adapter plates for the 7.3 and 6.0L diesel 6-speed. WE currently do not make a 5.4 or 6.8 6-speed adapter plate due to the small clutch that would have to be used with one. Ford 6-Speed – The 6-speed manual would be a very rare option in one of these trucks. See our Cummins to Ford 5R110 Torqshift article for more information. If you plan on doing some pulling, we would highly recommend getting a diesel torque converter.

TRANSMISSIONS 5.4 AND 6.8 AUTOMATIC TRANSMISSION SECTION The 5R110’s are a 5-speed automatic that comes behind the 2008-2010 5.4 and 6.8 Fords. The 2008-2010 Ford radiator and intercooler swap requires more parts than the earlier 2003-2007 models- and if the parts are bought brand new they are fairly expensive. Keep in mind that a new diesel exhaust system will also be required and a diesel radiator is also a good idea if you plan to do some considerable hauling. This is explained further in the installation manual. You should plan to drop the fuel tank and remove the electric fuel pump. There is not too much difficulty with this conversion, as these trucks have the same frame and transmission mounting as the diesel versions. Many times customers ask about converting 2008-2010 Ford® 5.4 and 6.8 trucks to a diesel due to the fact that they can be purchased reasonably, or they already have one and would like diesel power.
