自动变速器的高效和平稳运行依赖于其液压系统的性能，而液压系统中的油液则承担着润滑、冷却和传递动力的关键任务。然而，随着时间的推移，自动变速器油（ATF）会因为高温和压力而退化，这会影响系统的效能并可能导致故障。因此，在自动变速器的维修过程中，正确处理和使用旧油液是至关重要的。本文将探讨如何判断和更换自动变速器油液，以及正确处理旧油的方法。

The efficient and smooth operation of an automatic transmission depends on the performance of its hydraulic system, and the oil in the hydraulic system plays a key role in lubrication, cooling, and power transmission. However, over time, automatic transmission fluid (ATF) can degrade due to high temperatures and pressure, which can affect system efficiency and potentially lead to malfunctions. Therefore, it is crucial to properly handle and use old fluids during the maintenance process of automatic transmissions. This article will explore how to determine and replace automatic transmission fluid, as well as the correct methods for handling old oil.

判断自动变速器油液是否需要更换

Determine whether the automatic transmission fluid needs to be replaced

1. 视觉检查：

1. Visual inspection:

自动变速器油应呈透明的红色或金黄色。如果油液颜色变得异常黑或有烧焦的气味，通常意味着油液已经退化，需要更换。

Automatic transmission fluid should be transparent in red or golden yellow color. If the oil color becomes abnormally black or has a burnt smell, it usually means that the oil has degraded and needs to be replaced.

2. 油液水平与质量评估：

2. Oil level and quality assessment:

定期检查油液的水平并注意其质地。油液过低或过脏都可能是问题的迹象。使用试纸可以更准确地评估油液的状况。

Regularly check the level of the oil and pay attention to its texture. Low or dirty oil may be signs of a problem. Using test strips can more accurately evaluate the condition of the oil.

3. 车辆性能表现：

3. Vehicle performance:

自动变速器响应迟缓或异响等异常表现可能与油液状况不佳有关。这些症状表明可能需要对油液进行检查甚至更换。

Abnormal performance such as slow response or abnormal noise of automatic transmission may be related to poor oil condition. These symptoms indicate that the oil may need to be checked or even replaced.

正确更换自动变速器油液的步骤

Steps for correctly replacing automatic transmission fluid

1. 选择合适的油液：

1. Choose the appropriate oil:

使用制造商推荐的自动变速器油液。不同车型和自动变速器类型可能要求使用特定类型的油液。

Use the manufacturer's recommended automatic transmission fluid. Different vehicle models and automatic transmission types may require the use of specific types of fluids.

2. 准备工具与材料：

2. Prepare tools and materials:

准备油桶、油桶漏斗、扳手和新的油液过滤器（如果需要更换）。

Prepare oil drums, oil drum funnels, wrenches, and new oil filters (if replacement is required).

3. 安全措施：

3. Safety measures:

在开始之前，确保车辆处于水平地面上，挡位设置在“P”（停车挡），并施加手刹。

Before starting, make sure the vehicle is on a level surface, the gear is set to "P" (parking gear), and the handbrake is applied.

4. 排放旧油液：

4. Discharge old oil:

找到变速器底部的放油螺丝，并将其慢慢松开以放出旧油液。确保油液能够完全排出。

Find the drain screw at the bottom of the transmission and slowly loosen it to release the old oil. Ensure that the oil can be completely drained.

5. 更换油液过滤器与重新注油：

5. Replace the oil filter and refill the oil:

如果需要，更换油液过滤器。然后，通过加注口慢慢加入新油至推荐的水平。

If necessary, replace the oil filter. Then, slowly add new oil through the filling port to the recommended level.

6. 清除空气：

6. Clearing the air:

启动发动机，让变速器在行驶挡每个位置上怠速运转几分钟，以帮助从系统中清除空气。

Start the engine and let the transmission idle in each position of the driving gear for a few minutes to help clear air from the system.

7. 检查：

7. Final inspection:

再次检查油液水平和状况，确保一切正常。

Check the oil level and condition again to ensure everything is normal.
