Whn I lived up North I warmed up until I saw the temp needle begin to move. After while you get a feel for how long it will take for varying temperatures.

Remember, heating the engine doesn't warm up the transmission. The best way to warm up a car is to drive moderately until the temperature get's up to near normal.
