Delayed shifts, when cold could be either a weak/failing TFT sensor (transmission fluid temp sensor, which is located on the solenoid block) or sticking valves in the valve body.
[Edit] I just noticed that you was talking about an Explorer. But I am sure the above should still apply.
How many miles does it have on it and how often have you changed the fluid, before now?
