Expert Reply:

The type of fitting to use will depend on the thread type used on the transmission line fittings on your 2010 Ford F-150. If they are 1/2"-20 threads use kit # D13024. If they are 5/8"-18 use # D13025. If you can measure the diameter of the threaded part of a fitting on your truck that will tell us which one is correct.

If you are getting a kit such as # D13504 then the proper size hose is included. The standard hose is 11/32 inches inner diameter.
