Let the fluid drain completely. It may take some time for all the fluid to drain out.

6. Replace the Drain Plug:

Once the fluid has drained, clean the drain plug and the surrounding area. Replace the drain plug and tighten it to the proper torque specification using a torque wrench.

7. Locate the Fill Plug:

The fill plug is typically located on the side of the transmission pan. It may be a square or hexagonal-shaped plug.

8. Remove the Fill Plug:

Remove the fill plug using a wrench. This will allow you to add new fluid.

9. Add New Transmission Fluid:

Using a funnel, slowly pour the recommended amount of new transmission fluid into the fill hole.

10. Check Fluid Level:

Once you’ve added the fluid, replace the fill plug and tighten it securely. Start the engine and let it idle for a few minutes. Then, check the fluid level again. If necessary, add more fluid until it reaches the correct level.
