Looking for the manual transaxle drain plug on my wife’s IQ. Completed a 2001 Yaris gear oil change last week and it made such a difference. I know the IQ gearbox oil is supposed to be lifetime but i still would like to change it. There is 2 plugs under the IQ, one that looks like the Yaris gearbox oil drain plug and the other is an Allen key plug (photo attached). Could someone help me please or even better direct me to a workshop manual 🧑🏽‍🔧
