I am NOT 100% sure but I believe the only differences between those trans are internal. So, you shouldn't have to change anything.

Externally they should be identical. I can't think of anything else you would need to swap over.

The solenoid pack on the 1995 and up vehicles are electrically different from the earlier versions. Ford moved the protection diodes from the solenoid pack to the PCM. Using a later model solenoid pack on an earlier truck will leave your PCM open to possible damage.

The diodes are used to suppress the voltage spike when power is removed from the solenoids in the solenoid pack. You can swap your old solenoid pack on to the newer transmission.
