How do you check transmission fluid on a 2003 Cadillac CTS?

To check the Transmission Fluid on a 2003 Cadillac CTS, first ensure the vehicle is parked on a level surface and the engine is running. Locate the transmission dipstick, which is usually near the back of the engine; pull it 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, and the color should be a clear red. If the fluid level is low or the color is dark or burnt, consider adding fluid or having it inspected by a professional.
