I know it has something to do with the transmission, but what exactly is happening?

There is a split second when the gears are spinning but the clutch is not engaged. This means that the car is getting no power to the wheels. When it catches on the gears, one the gears have to slow a bit because they went from spinning with no resistance to spinning with the weight of the car as resistance. Two the car can suddenly start accelerating again because the wheels are receiving torque (power) again after a split second of not.
