Hey all, as soon as its warm enough I will be helping a friend change the ATF in a car that he just picked up, a 1995 Cavalier Z24 with the 4T40-E transmission. I have a few questions; how hard is it to do a pan drop on this transmission, how many quarts will we need for just a pan drop, and what fluid brand works best in this application? I'm partial to Castrol Transmax but he is open to anything. Thanks!
