Time, time to stop time to think, it takes time to:signal the transmission via the selector, then through wires to the solenoid and then through hydraulic pressures to finally engage. All this just doesn't happen at once, although the transmission does its best as a hydraulic, mechanical device with electric solenoids for primary action followed up with hydraulic action placed on spinning plates and friction material.
Your robust actions can cause excessive hydraulic action to force material into the hydraulic parts of a solenoid and cause delay. Remember that a solenoid is only the primary mover, the electric part and that acts on pressure of the hydraulics. If the car is cold the idle is fast to improve warm up time but the transmission oil pressures are higher than normal and cold. Cold oil is more dense, take a bit more to flow. The transmission oil will take 2x as long to warm up as the coolant in the engine.
When cold treat the vehicle like you like it, that you want to keep it. Transmission work on vehicles is expensive, most mechanics know not, but a good transmission guy is good at mechanics, electrical and hydraulics and you will have to pay his price.
If you can't wait 3 seconds to shift from P to R to D when cold, try driving a standard shift because you will have to learn to handle a clutch.
Slow down, the world will wait for you.
BTW if further problems are showing up there may be particles hanging in the fluid of the transmission and a fluid change usually gets them out. Check your internal filter.
