What Does Automatic Transmission Fluid Inspection Include?
1 Answers
Automatic transmission fluid inspection should include checking the fluid level, fluid quality, and potential leakage points. During the transmission fluid inspection process, it is crucial to maintain cleanliness to prevent dust particles from entering the transmission, which could lead to premature transmission failure. If abnormal transmission fluid levels are observed, begin with a simple visual inspection to identify obvious leaks or other issues. It is recommended to take the vehicle to an authorized after-sales service center for professional inspection and troubleshooting. Here are the relevant details: 1. Low automatic transmission fluid level: This condition may cause the oil pump to draw in air, resulting in aerated fluid that reduces oil pressure and slows pipeline pressure buildup. It leads to inadequate lubrication of planetary gear systems, clutch and brake slippage, and deteriorated acceleration performance. Low fluid levels are typically caused by external leaks. The cause should be identified and fluid should be replenished according to specifications. 2. High automatic transmission fluid level: Rotating planetary gears can agitate the fluid, causing air entrainment and foam formation. Overfilled fluid may also overheat and oxidize, forming sludge that affects the normal operation of valves, clutches, and brake servo cylinders. Excessively high fluid levels may cause fluid to spray from the filler tube or vent pipe, potentially leading to engine compartment fires. High fluid levels are usually caused by overfilling. The solution is to extract excess fluid through the filler tube or drain the surplus through the drain plug.
