Checking your transmission fluid is an essential part of routine car maintenance, but many car owners are unaware of the importance of doing it while the engine is running. This seemingly small detail can make a big difference in the accuracy of your reading and ultimately the health of your transmission.
Why Check While Running?
When your car is off, the transmission fluid settles to the bottom of the pan. This can give you a false reading, leading you to believe your fluid levels are adequate when they’re actually low. Running the engine allows the fluid to circulate throughout the system, providing a more accurate representation of the actual fluid level.
How to Check Transmission Fluid
- Warm up the engine⁚ Let the engine run for a few minutes to allow the fluid to reach its optimal temperature.
- Locate the dipstick⁚ The transmission dipstick is usually located on the driver’s side of the engine compartment. It’s often marked with a “T” or “Transmission.”
- Remove and wipe the dipstick⁚ Pull the dipstick out and wipe it clean with a clean cloth or paper towel.
- Insert and remove again⁚ Insert the dipstick fully back into the tube and then remove it once more.
- Check the fluid level⁚ The fluid level should be between the “Full” and “Add” markings on the dipstick. If the level is low, add transmission fluid as needed.
What to Look For
Besides the level, you should also pay attention to the fluid’s color and smell. Fresh transmission fluid is typically a reddish-pink color. If the fluid is dark brown or black, it’s likely contaminated and needs to be replaced. A burnt smell can also indicate a problem with the transmission.
Consequences of Low Transmission Fluid
Running your transmission with low fluid can lead to serious damage, including⁚
- Overheating⁚ Transmission fluid helps to cool the transmission, and low levels can lead to overheating.
- Reduced performance⁚ Low fluid can cause slipping, rough shifting, and even transmission failure.
- Increased wear and tear⁚ Without enough fluid, the transmission components experience increased friction and wear.
Conclusion
Checking your transmission fluid while the engine is running is a simple but crucial step in maintaining your car’s health. By following the steps above, you can ensure your transmission is properly lubricated and operating at its best. Regular fluid checks can prevent costly repairs and keep your car running smoothly for years to come.
