- Drain pan
- Funnel
- Rags or paper towels
- 1/2-inch socket wrench or adjustable wrench
- Torque wrench (optional)
Step-by-Step Instructions
1. Locate the Drain Plug
Identify the drain plug located at the bottom of the transmission housing. It’s typically a 1/2-inch hex bolt.
2. Drain the Old Oil
Place the drain pan underneath the drain plug. Carefully loosen the plug using the socket wrench or adjustable wrench. Allow the old oil to drain completely.
3. Clean the Drain Plug
Wipe the drain plug and the surrounding area with a rag to remove any debris or old oil.
4. Replace the Drain Plug
Apply a small amount of thread sealant to the drain plug threads to prevent leaks. Tighten the plug securely using the socket wrench or adjustable wrench.
5. Locate the Fill Plug
Find the fill plug, which is usually located near the top of the transmission housing. It’s typically a 1/2-inch hex bolt with a dipstick attached.
6. Add New Gear Oil
Insert the funnel into the fill hole. Slowly pour the recommended amount of new gear oil into the transmission.
7. Check the Oil Level
Remove the dipstick and wipe it clean. Reinsert the dipstick and check the oil level. It should be between the “Full” and “Add” marks on the dipstick.
8. Tighten the Fill Plug
Remove the funnel and tighten the fill plug securely using the socket wrench or adjustable wrench. If available, use a torque wrench to tighten the fill plug to the manufacturer’s specifications.
