How often should the transmission fluid be changed for the Malibu?
1 Answers
Under normal driving conditions, the transmission fluid should be changed every 2 years or 60,000 kilometers. For specific details, refer to the vehicle's maintenance manual. If the transmission fluid is not changed over a long period, its lubricating effectiveness will diminish, leading to inadequate lubrication, which can affect the hydraulic system's performance and cause unstable transmission pressure. Below are relevant details: 1. Transmission fluid is an oil product used to keep the gear system clean, ensuring the transmission operates normally and extending the lifespan of the transmission components. Failure to change the transmission fluid regularly can result in: impurities forming due to chemical changes in the fluid, leading to blocked oil passages and affecting gear-shifting functionality. Prolonged high-temperature operation reduces the lubricating properties of the transmission fluid, increasing the risk of clutch plate wear and causing stalling. 2. It is important to note that when changing the transmission fluid, not only the fluid itself needs to be replaced, but two other components should also be addressed. One is the transmission fluid filter, which functions similarly to an oil filter by removing impurities from the lubricating fluid. The second is cleaning the transmission fluid pan. If possible, the pan should be removed to reveal a thick layer of sludge mixed with metal shavings. If not cleaned thoroughly, even new transmission fluid will be significantly less effective. Additionally, when reinstalling the pan, always replace the sealing gasket to ensure proper sealing.
