What Causes an Automobile Transmission to Overheat?
1 Answers
Reasons for automobile transmission overheating include: 1. Insufficient lubricating oil in the transmission or the use of lubricating oil with an incorrect specification; 2. Overly tight bearing assembly; 3. Overly tight gasket and washer assembly; 4. Excessively small meshing clearance in newly replaced gears. The normal operating temperature range for transmission oil is between 90 to 100 degrees Celsius. Prolonged exposure to temperatures above this upper limit can cause severe damage to the transmission. 90% of transmission failures are caused by high temperatures. High temperatures in the transmission do not exhibit obvious fault symptoms during use, but prolonged high temperatures can lead to aging of internal seals, brittleness of plastic components, degradation of the lubricating properties of the oil, and reduced lifespan of electrical components. It is essential to regularly measure the transmission oil temperature and address any issues promptly.
