Checking your transmission fluid level is a crucial part of regular vehicle maintenance. However, the question of whether you should run the engine while checking the fluid often arises. The answer is a resounding “no.” It’s best to check your transmission fluid level with the engine off and the vehicle parked on a level surface.

Why Check Transmission Fluid with the Engine Off?
- Safety First⁚ A hot engine and transmission present a significant burn risk. Running the engine increases the temperature of the fluid, making it more dangerous to handle.
- Accurate Reading⁚ When the engine is running, the transmission fluid circulates, making it difficult to get an accurate reading. The fluid level can fluctuate, leading to incorrect interpretations.
- Fluid Viscosity⁚ Cold transmission fluid is thicker and provides a more accurate level reading. Running the engine warms the fluid, making it thinner and potentially skewing the measurement.
How to Check Transmission Fluid Level⁚
- Park on a Level Surface⁚ Ensure your vehicle is parked on a flat, level surface. This will guarantee an accurate reading.
- Locate the Dipstick⁚ The transmission dipstick is usually located near the engine or transmission area. It’s often marked with a “T” or “Trans” symbol.
- Remove and Wipe⁚ Carefully pull out the dipstick, wipe it clean with a clean cloth or paper towel, and reinsert it fully.
- Check the Level⁚ Remove the dipstick again. The fluid level should be within the “Full” marks on the dipstick. If the level is low, you may need to add more fluid.
Important Notes⁚
- Always use the correct type of transmission fluid for your vehicle, as specified in your owner’s manual.
- Overfilling the transmission can cause problems, so it’s crucial to only add fluid if the level is low.
- If you notice a burnt smell, unusual color, or excessive debris in the transmission fluid, it’s essential to have your transmission inspected by a qualified mechanic.
Checking your transmission fluid level with the engine off ensures accuracy and safety. By following these steps, you can maintain the health of your transmission and prevent potential issues down the road.
