Where do you put transmission fluid in a 2003 Cadillac CTS?

To add Transmission Fluid to a 2003 Cadillac CTS, locate the transmission dipstick tube, which is typically found near the back of the engine bay. Remove the dipstick, wipe it clean, and then insert it back to check the fluid level. If you need to add fluid, use a funnel to pour it into the dipstick tube, ensuring you use the correct type of transmission fluid specified in your owner's manual. Always check the fluid level again after adding to ensure it's at the proper level.
