What You’ll Need
- New transmission fluid⁚ Refer to your Smart Car’s owner’s manual for the specific type and quantity required.
- Drain pan⁚ A large capacity pan to collect the old fluid.
- Torque wrench⁚ For accurate tightening of bolts.
- Jack and jack stands⁚ To safely elevate the car.
- Socket wrench set⁚ To loosen and tighten bolts.
- Gloves⁚ To protect your hands from the hot fluid.
- Clean rags⁚ For wiping spills and cleaning.

Step-by-Step Guide
1. Preparation
- Park on a level surface and engage the parking brake.
- Locate the transmission fluid pan⁚ It’s typically located on the underside of the car, near the transmission.
- Warm up the engine⁚ Run the engine for a few minutes to allow the transmission fluid to reach operating temperature. This will ensure a more complete fluid drain.
2. Draining the Old Fluid
- Place the drain pan under the transmission pan.
- Locate the drain plug⁚ It’s usually a square or hexagonal-shaped plug on the bottom of the pan.
- Carefully loosen the drain plug using a socket wrench. As you loosen it, be prepared for hot fluid to start flowing out.
- Let the fluid drain completely. You may need to remove and reinsert the drain plug a few times to ensure all the old fluid is out.
3. Replacing the Drain Plug
- Clean the drain plug and the surrounding area of any debris.
- Replace the drain plug and tighten it securely using a torque wrench. Refer to your owner’s manual for the recommended torque specification.
4. Filling with New Fluid
- Locate the transmission fluid fill tube⁚ It’s often located on the side of the transmission. It may be a small opening with a dipstick or a larger opening with a cap.
- Carefully pour the new transmission fluid into the fill tube using a funnel.
- Check the fluid level⁚ Use the dipstick or consult your owner’s manual for the correct fluid level.
- Add more fluid if needed.
5. Final Steps
- Start the engine and run it for a few minutes. This will allow the fluid to circulate throughout the transmission.
- Re-check the fluid level and add more if necessary.
- Clean up any spills and dispose of the old fluid properly. Contact your local recycling center for disposal guidelines.
Important Notes
- Always follow the instructions in your Smart Car’s owner’s manual. It will provide the specific fluid type, capacity, and torque specifications for your vehicle.
- Use caution when working with hot fluids. Wear gloves and protective eyewear.
- If you’re not comfortable performing this task, consult a qualified mechanic. Improper fluid changes can damage your transmission.
