Locate the Drain Plug
The transmission drain plug is typically located on the bottom of the transmission case. It may be a square or hexagonal plug. You can consult your owner’s manual or an online repair guide for your specific vehicle to confirm its location.
Drain the Old Fluid
1. Position the drain pan underneath the drain plug.
2. Carefully loosen and remove the drain plug. Be cautious, as the fluid will be hot.
3. Allow the fluid to drain completely. This may take several minutes.
4. Once the fluid stops draining, replace the drain plug and tighten it securely. If you’re using a torque wrench, refer to your owner’s manual for the recommended torque setting.
Fill the Transmission with New Fluid
1. Locate the transmission dipstick. It is usually located near the transmission pan.
2. Remove the dipstick and carefully pour the new transmission fluid into the dipstick tube. Use a funnel to avoid spills.
3. Check the fluid level regularly using the dipstick. Refer to your owner’s manual for the correct fluid level. You may need to add more fluid in stages to reach the proper level.
Important Notes
- Transmission fluid is typically a bright red color. If the fluid is dark brown or black, it’s a sign that it’s time for a change.
- Don’t overfill the transmission. Too much fluid can cause problems with the transmission’s operation.
- If you’re unsure about any part of this process, it’s best to consult a qualified mechanic.
