Close-up of transmission fluid being poured into car engine – The 2004 Cadillac CTS, a model that debuted just a year earlier, came standard with a 3.2-liter V-6 engine that cranked out a respectable 220 horsepower. For buyers who needed a little more “umph” out of their V-6 engine, Cadillac also offered the optional 3.6-liter, high-feature, V-6 engine — typically called the HFV6, which pumped out 255 horsepower. Checking the automatic transmission fluid in the HFV6-equipped CTS is something Cadillac claims is unnecessary, so the car is not equipped with a transmission dipstick. For in-the-know mechanics who understand periodic inspection of the fluid is necessary, Cadillac did fit a check-and-fill plug on the transmission for checking the level.
