How to add manual transmission fluid?


Adding manual transmission fluid is an essential maintenance task for vehicles with manual transmissions. Proper lubrication is crucial for the smooth operation of the transmission and extending its lifespan. In this article, we will guide you through the process of adding manual transmission fluid, ensuring that you can perform this task with confidence.

Gather the Necessary Tools and Materials

Before starting, it is important to gather all the tools and materials required for the task. Here are the items you will need:

– Manual transmission fluid (refer to your vehicle’s manual for the recommended type)
– Funnel

– Jack and jack stands (if needed)
– Safety goggles
– Gloves
– Rags or paper towels

Locate the Transmission Fill Plug

To add manual transmission fluid, you need to locate the transmission fill plug on your vehicle. The location of the fill plug may vary depending on the make and model of your vehicle. Typically, it is located on the side or top of the transmission housing. Refer to your vehicle’s manual or consult a reliable online source to find the exact location.

Prepare the Vehicle

Before proceeding, ensure that your vehicle is on a level surface and the engine is turned off. If necessary, use a jack and jack stands to lift the vehicle safely and securely.

Drain the Old Fluid (if applicable)

Some vehicles may require draining the old transmission fluid before adding new fluid. If your vehicle falls into this category, locate the transmission drain plug and carefully remove it. Allow the old fluid to drain completely into a suitable container. Once drained, reinstall the drain plug securely.

Add the New Transmission Fluid

With the old fluid drained (if applicable), it’s time to add the new transmission fluid. Follow these steps:

1. Position the funnel securely into the transmission fill plug opening.
2. Slowly pour the new transmission fluid into the funnel. Be cautious not to overfill, as it can lead to transmission issues.
3. Periodically check the fluid level by removing the fill plug. If the fluid starts to overflow, it indicates that the transmission is adequately filled.
4. Once the fluid level is correct, reinstall the fill plug securely.


Adding manual transmission fluid is a relatively straightforward process that can help maintain the performance and longevity of your vehicle’s transmission. By following the steps outlined in this article, you can confidently perform this essential maintenance task. Remember to consult your vehicle’s manual for specific instructions and recommended fluid types.
