What model of transmission: AODE, E4OD?
Your F150 probably has the AODE in it. In either case, the unit needs to be scanned. You may find electrical issues with the solenoids all late model transmissions now have. The solenoids include a dual pack shift solenoid, a TCC solenoid and a pressure control solenoid, along with an output speed sensor, a vehicle speed sensor, a manual lever position switch and others. On late model transmissions, a knowledgeable rebuilder will scan the unit first while on the road test.. A good rebuilder will have the equipment to check these electronic items and replace them as needed.
Just my two bits worth.
