My understanding is that you keep the car running until it's optimum temperature then check the dipstick while car is running, correct?

Hello BHAMDOC,

You are correct, you check the transmission fluid with the engine/trans fully warmed up. Attached is an image of the written service procedure for your reference.

Please use caution and let us know if you have any questions on this procedure.

Thanks!
