Usually, when changing automatic transmission oil, the lower drain hose is removed. Here are the steps you need to follow:
1. Raise the vehicle: Raise the vehicle using a jack and support it on jack stands for safety.
2. Locate the automatic transmission drain hose: The automatic transmission drain hose is usually located on the oil pan. This is a flexible rubber hose with a diameter of about 1-2 cm.
3. Prepare a container to receive the oil: Place a drain container under the drain hose.
4. Loosen the hose clamp: Locate the clamp clamp that secures the drain hose to the oil pan. Loosen the clamp using pliers or a screwdriver.
5. Remove the drain hose: Gently pull the drain hose to remove it from the oil pan.
6. Drain the automatic transmission oil: Allow the oil to drain into the drain container. Be careful as the oil may be hot.
7. Replace the drain hose: After the oil has drained, install the drain hose back onto the oil pan. Tighten the clamp to secure the hose.
8. Lower the vehicle: Lower the vehicle from the stands.
Note:
* Some car models may have several automatic transmission drain hoses. In this case, it is necessary to remove all drain hoses to completely drain the oil.
* It is recommended to replace the O-ring on the drain hose every time it is removed.
