How do you check transmission fluid in a 2004 Cadillac CTS?

To check the Transmission Fluid in a 2004 Cadillac CTS, first ensure the vehicle is parked on a level surface and the engine is running at normal operating temperature. Locate the transmission dipstick, which is typically near the back of the engine bay. Pull the dipstick out, wipe it clean, reinsert it, and then remove it again to check the fluid level. The fluid should be within the marked range on the dipstick; if it's low, add the appropriate type of transmission fluid as specified in the owner's manual.
