just rolled over 23k on my malibu, when i hit 25k i plan on doing a drain and fill on the trans. its has a drain plug and a check plug. i think the trans holds about 12Q, but a drain and fill i think is 4-5Q. i plan on doing this every 25k. was thinking about useing valvoline maxlife dextron VI, good choise or use soming else? also do you think it would be worth it to have a UOA done on the FF trans fluid?
