How often should the transmission fluid in a Lincoln MKC be changed?
2 Answers
Under normal driving conditions, the transmission fluid should be changed every 2 years or 60,000 kilometers. For specific details, please refer to the vehicle's maintenance manual. If the transmission fluid is not changed for an extended period, its lubricating effectiveness will diminish, leading to inadequate lubrication. This can affect the operation of the hydraulic system and cause unstable pressure in the car's transmission. Below is an introduction to the methods for changing transmission fluid: 1. Gravity Drain: This method works on the same principle as changing engine oil. Loosen the bolt on the oil pan and allow the transmission fluid to drain out under gravity. While simple, this method does not completely remove all the old fluid, as residual fluid may remain in recesses and dead corners. 2. Machine Flush: New transmission fluid is stored in a flushing machine, which is connected to the transmission via pipes. The new fluid pushes out the old fluid under the action of the machine. This method cleans the fluid passages more thoroughly. The more new fluid used, the cleaner the system becomes. A machine flush typically requires about 12 liters or more of new transmission fluid, making it more expensive. The process also takes longer, usually around an hour. 3. Oil Pan Removal: This method cleans the system from the root, ensuring a more thorough cleaning. Additionally, the transmission fluid filter can be cleaned during this process.
I've been driving a Lincoln MKC for several years, and the transmission fluid change interval is quite important—it's not something to take lightly. Generally speaking, based on my experience, it should be replaced every 30,000 to 60,000 miles, but the exact timing depends on driving habits and the manual's recommendations. If you frequently encounter city traffic jams, the transmission works harder, and the fluid tends to degrade faster. I usually recommend changing it earlier, around 40,000 miles. If you delay the change, deteriorated fluid can lead to gear wear, rough shifting, or even costly transmission overhauls. Don’t forget to check the fluid's color and smell—if it turns black or has a burnt odor, act immediately. It’s best to have a professional shop evaluate it regularly. Don’t skimp to save a few bucks—spending a few hundred dollars on a fluid change is far better than paying thousands for repairs.
