To change the transmission fluid on a 2004 Cadillac SRX, start by warming up the vehicle to thin the fluid for easier drainage. Then, safely lift the vehicle and place it on jack stands. Remove the transmission pan bolts, allowing the old fluid to drain into a pan, and then replace the filter if applicable. Once the pan is clean, reattach it with a new gasket, refill the transmission with new fluid through the dipstick tube, and check the fluid level according to the manufacturer's specifications.
The automatic transmission fluid in a 2004 Ford Mustang should be changed every 30,000 miles or once a year. The manufacturer has made this recommendation available in the owner's manual as well.
