2007 Ford Freestyle AWD Limited:

My wrench light comes on after car is warm but does not throw any codes. Turn the car off and on wrench light goes away. Put it in any gear after restarting and still warm the light comes back on. When this happens the reverse lights will stay on in any gear. While driving the car runs and shifts great. When warm and shifting from park it shifts hard but shifts smooth when driving. The reverse lights are my biggest concern at the moment.

When a warning light comes on, there's a code stored in the computer....always. There are generic codes that inexpensive code readers can read and there are manufacturer specific codes that require very expensive professional scan tools. If you didn't use a pro scan tool, that's why you're not seeing the code. Computers don't turn on the light for no reason at all.
