Recently the car seems to hesitate when accelerating uphill in the morning when I leave my house (before it's warmed up). After getting up to highway speed, it works flawlessly.

Could it be a dirty throttle body, MAF sensor or the transmission? I have the car in Overdrive, does this make a difference?
