Why You Should Never Add Transmission Fluid While the Car Is Running
- Safety Hazard⁚ Adding fluid to a running transmission can lead to hot fluid spraying out, posing a serious burn risk. The moving parts within the transmission also create a significant risk of injury if you’re not careful.
- Fluid Contamination⁚ Adding fluid while the engine is running can introduce air into the transmission system, leading to air bubbles that can cause damage and affect performance.
- Overfilling⁚ It’s difficult to accurately assess the fluid level while the engine is running, making it easy to overfill the transmission. This can lead to excessive pressure and damage to the transmission seals and internal components.
- Fluid Mixing⁚ Adding the wrong type of fluid to a running transmission can cause chemical reactions that can damage the transmission. Always consult your owner’s manual for the correct fluid type.
The Proper Way to Check and Add Transmission Fluid

- Wipe the dipstick clean with a rag.
- Insert the dipstick fully and then remove it again.
- Check the fluid level on the dipstick.
- Add fluid as needed, ensuring you use the correct type.
- Replace the dipstick and check the fluid level again after driving a short distance.
When to Consult a Mechanic
