Yes, warm it up in every gear, even if you have to do it parked. The fluid needs to warm up to reduce viscosity before you drain it. You also want to stir up any settled particles so that they're suspended in the fluid while it drains.

One more day/week will not make a difference changing the xmission oil/filter. Besides, you need the engine hot to check the oil level after you add the new oil.
