What brand of transmission fluid does Cadillac use?
3 Answers
"The transmission fluid used in this vehicle is from the Mobil brand. Cadillac transmission fluid replacement interval: Cadillac transmission fluid should be replaced every 2 years or 40,000 kilometers. If the transmission fluid is used for too long without replacement, it may lead to reduced power, rough and unsteady gear shifting, and abnormal noises from the transmission. Once these symptoms appear, the transmission condition should be checked and the fluid replaced promptly. Transmission maintenance methods: Regularly check whether the automatic transmission fluid level is normal. To check the transmission fluid, it needs to be preheated to about 50 degrees Celsius, then shift the gear lever through each position for 2 seconds before placing it in park. At this time, the normal fluid level on the dipstick should be between the maximum and minimum lines. If it is insufficient, add the same quality fluid promptly. Follow the recommended transmission fluid replacement interval. The correct method for changing transmission fluid currently is dynamic fluid replacement, using specialized transmission cleaning equipment."
When I drove my Cadillac CTS, I used Dexron VI transmission fluid, which is the brand recommended by GM itself. Compatible products from brands like ACDelco or Valvoline are also available. It’s not always necessary to stick with the original brand—the key is to ensure the fluid specifications match your vehicle’s model manual requirements. I found that it made shifting smoother and extended the lifespan. If you have a newer model like the XT5, it might support the latest specifications. I must emphasize that regular fluid changes are crucial—typically every 40,000 to 60,000 kilometers for inspection or replacement. Don’t cheap out and buy off-brand products, as it can lead to transmission wear and issues like jerking or leaks. During maintenance, ask the technician to check the fluid quality with a diagnostic tool to ensure driving safety. My personal advice is to first check the owner’s manual for the exact specifications before choosing a brand.
As someone who frequently repairs Cadillacs, I recommend using brands compatible with Dexron VI, such as Mobil 1 and Castrol. These major brands are quite reliable. In actual maintenance, we often encounter failures caused by the indiscriminate use of cheap oils, such as poor oil quality leading to transmission overheating or noise. You need to consider whether the fluid viscosity and high-temperature stability match your vehicle model. I suggest changing it approximately every 50,000 kilometers, especially if you drive frequently. Checking the oil level is also part of routine maintenance to prevent damage from insufficient oil. Don't overlook the small details—ensure the oil passages are cleaned during oil changes to extend the transmission's lifespan and save hassle.
