It's a very common complaint, even has its own tsb so every dealership should know the fix.

the hardness isn't so much a problem as it is a byproduct of Ford Engineers.
The TCM is intentionally programmed to shift harder when tranny temps are colder. This is done to save on wear/tear of the tranny.
Unfortunately, they went a bit too firm. The TSB addresses this. Do you ever notice the problem when the temperatures are warmer (ie: summer)?
