A list of everything you will need in order for the drivetrain to operate.
For nearly all Duramax drivetrains there are a few basic items that are common and will be needed for all donors.

It is important that you take some time to clean the harness and control modules to the best of your ability to avoid extra fees for cleaning, super dirty, or oily control, modules or harnesses.
In order for us to build and program the appropriate calibration for your engine control, module and transmission control module you will need to ship both of the modules in careful packaging to the appropriate address in ordering guide.
Be sure to watch our YouTube video at the end of the ordering guide to help understand which portion of the harness we need. Make sure you don’t leave any extra unnecessary wiring in your shipment as that will add additional shipping costs when returning your components.
You will also box up your ECM/TCM harness and ship it to the appropriate address in the ordering guide. These parts are expensive and many of them are no longer produced by GM so take some care and packaging your parts to prevent costly damage.
If you have any questions about your donor or any of its components, feel free to email us.
