[McEmery]

Buick LaCrosse transmission fluid replacement can be divided into two steps: 1. Remove the transmission oil pan, take out the filter, and clean the oil pan thoroughly. 2. Then install a new filter and reassemble the oil pan, followed by adding new transmission fluid. Depending on the transmission structure, transmission fluid is categorized into manual transmission fluid and automatic transmission fluid. Below are the relevant details: 1. Manual transmission fluid, commonly referred to as gear oil. It is primarily composed of petroleum-based lubricating oil or synthetic lubricating oil, blended with extreme pressure anti-wear agents and oiliness agents to form an essential lubricant. Used in various gear transmission devices to prevent gear surface wear, scuffing, sintering, etc., thereby extending service life, improving power transmission efficiency, and reducing power loss. 2. Automatic Transmission Fluid (ATF) is specifically designed for automatic transmissions. The dedicated fluid used serves as the hydraulic fluid for the torque converter, the lubricating oil for the planetary gear structure, and the hydraulic oil for the shifting mechanism. Under normal driving conditions, ATF should be replaced every 120,000 kilometers, while under severe driving conditions, it should be replaced every 60,000 kilometers.
