Hello, I want to change the transmission oil in my 93 Accord. I'd like to drain as much as possible as I believe some remains behind when the drain plug is removed. I've been told you can run the engine while it's in park to swirl the oil from the torque converter. Is this true? Or you can remove the oil line to the radiator and pump it out. What is the best way as I want to do it right first time.
