Your car’s transmission fluid is essential for smooth gear changes and overall drivetrain health. Regularly checking its level and condition is crucial to prevent costly repairs. But when is the best time to do it⁚ when the engine is running or off?

Checking Transmission Fluid When the Engine is Running
Generally, it’s not recommended to check your transmission fluid while the engine is running. Here’s why⁚
- Safety hazard⁚ Moving parts and hot fluids pose a risk of burns or injury.
- Inaccurate readings⁚ The fluid level can fluctuate when the engine is running, making it difficult to get an accurate reading.
- Fluid pressure⁚ The transmission system is under pressure when the engine is running, making it difficult and potentially dangerous to access the dipstick.
Checking Transmission Fluid When the Engine is Off
The best time to check your transmission fluid is when the engine is cold and off. Here’s how⁚
- Park your car on a level surface and engage the parking brake.
- Locate the transmission dipstick. It’s usually located near the back of the engine, often with a yellow or orange handle.
- Wipe the dipstick clean with a rag.
- Insert the dipstick fully into the dipstick tube and then remove it.
- Check the fluid level on the dipstick. It should be between the “Full” and “Add” markings. If it’s below the “Add” mark, add fluid as needed.
- Inspect the fluid’s condition. It should be clear, red, and smell slightly sweet. If it’s dark, burnt, or smells burnt, it may need to be replaced.
Important Notes⁚
- Consult your owner’s manual⁚ It provides specific instructions for your car model.
- Use the correct type of transmission fluid⁚ Refer to your owner’s manual or consult a mechanic.
- Regular maintenance⁚ Transmission fluid should be changed according to the manufacturer’s recommendations or every 30,000 to 60,000 miles.
By checking your transmission fluid regularly, you can help ensure the smooth operation of your car’s drivetrain and avoid costly repairs down the road.
