If you warm up while idling the engine will be ready to give out what it has but other components are simply not ready to handle the load. Also bear in mind that a proper warm up of the transmission is at least 20-25km of driving as the transmission fluid is very hard to heat up and cool down. If you start putting pedal to the metal before that I can guarantee that it will give you headache on the longer run.
This is interesting because when I did my transmission fluid change I idled the car until the tranny fluid temps raised for proper fill level. So to say that transmission doesn't warm up during idle is not correct.
