Step-by-Step Guide

1. Locate the Transmission Drain Plug

The transmission drain plug is located on the bottom of the transmission pan. It is usually a square or hexagonal-shaped plug.

2. Drain the Old Transmission Fluid

Place the transmission fluid drain pan underneath the drain plug. Using a wrench, loosen and remove the drain plug. Allow the old transmission fluid to drain completely into the pan.

3. Replace the Drain Plug

Once the fluid has drained, clean the drain plug with a clean rag and reinstall it; Make sure to tighten it to the correct torque specification, which can be found in your owner’s manual.

4. Locate the Transmission Fill Plug

The transmission fill plug is usually located on the side of the transmission pan. It is usually a smaller plug than the drain plug.

5. Fill with New Transmission Fluid

Using a funnel, carefully pour the new transmission fluid into the transmission fill plug hole until it starts to overflow. This indicates that the transmission is full.

6. Replace the Fill Plug

Clean the fill plug with a clean rag and reinstall it. Make sure to tighten it to the correct torque specification.

7. Start the Car and Check the Fluid Level

Start the car and let it run for a few minutes to circulate the new fluid. Then, shut off the engine and check the fluid level again. If it is low, add more fluid until it reaches the proper level.

8. Check for Leaks

After you have filled the transmission with new fluid, inspect the area around the drain and fill plugs for any leaks. If you see any leaks, tighten the plugs and check again.

9. Dispose of the Old Transmission Fluid Properly

Dispose of the old transmission fluid properly. Do not pour it down the drain. Check with your local recycling center or auto parts store for disposal options.
