How can I warm up my transmission faster?
Revving the engine makes it spin faster and therefore heat up faster. Holding the car still while you rev in gear makes the engine spin more, but the transmission cannot spin more because you are holding the wheels still, so it puts pressure on the clutch and torque converter which have to absorb the energy.
