How do you change ATF in a Vauxhall corsa?

To change the automatic Transmission Fluid (ATF) in a Vauxhall Corsa, first ensure the vehicle is on a level surface and the engine is warm. Locate the transmission oil drain plug and remove it to drain the old fluid into a suitable container. After draining, replace the drain plug, then use a funnel to refill the transmission with the appropriate ATF through the fill plug, checking the level with the dipstick as you go. Always consult the owner's manual for specific fluid type and capacity.
