Materials You’ll Need
Before you start, gather the following materials:
- New gear oil (check your owner’s manual for the recommended type and amount)
- Drain pan
- Funnel
- New crush washer for the drain plug
- 19mm socket wrench
- Rags or gloves
Step-by-Step Instructions
1. Safety First
Park your Corolla on a level surface and engage the parking brake. Allow the engine to cool down completely.
2. Locate the Drain Plug
The drain plug is located on the bottom of the transmission pan. It’s a 19mm bolt with a crush washer.
3. Place the Drain Pan
Position the drain pan under the drain plug to catch the old gear oil.
4. Remove the Drain Plug
Use the 19mm socket wrench to carefully loosen the drain plug. Be careful not to drop the bolt into the pan. Allow the old gear oil to drain completely.
5. Replace the Crush Washer
Once the old oil has drained, replace the crush washer on the drain plug. This is important to prevent leaks.
6. Reinstall the Drain Plug
Tighten the drain plug back into the transmission pan using the socket wrench. Do not overtighten.
7. Add New Gear Oil
Use the funnel to pour the new gear oil into the transmission fill plug. Fill it to the recommended level (check your owner’s manual).
8. Check the Oil Level
Start the engine and let it run for a few minutes. Then, turn off the engine and check the oil level again. Add more oil if necessary.
9. Reset the Trip Odometer
After you’ve changed the gear oil, reset the trip odometer so you can track when it’s time to change it again.
