What are the causes of automatic transmission lubricant deterioration?
1 Answers
Automatic transmission lubricant deteriorates due to the following reasons: 1. The automatic transmission oil specification does not meet the required standards; 2. Incomplete oil change, where only the oil in the oil pan is replaced, while the oil in the torque converter and radiator remains unchanged; 3. Engine coolant entering the automatic transmission cooling oil circuit; 4. Improper vehicle usage, frequently overloading or driving abnormally; 5. Blockage in the automatic transmission radiator or pipelines, or jamming of the radiator's pressure relief valve; 6. Excessive or insufficient clearance in the clutch or brake, or too small clearance in moving parts; 7. Insufficient main oil circuit pressure, causing slippage in the clutch or brake during engagement; 8. Malfunction in the torque converter.
