Why Does a Car Need to Be Running to Check the Automatic Transmission Fluid Level?
Checking the automatic transmission fluid (ATF) level is crucial for maintaining optimal performance and longevity of your car's transmission. However, many people question why it's necessary to have the engine running during this process.
Reason: Circulating Fluid
ATF circulates throughout the transmission to lubricate components, dissipate heat, and transfer power. When the engine is running, the transmission fluid pump forces ATF through the various components, ensuring that the fluid level is accurate.
Accurate Measurement
If the engine is not running, the ATF will settle at the bottom of the transmission pan, resulting in an inaccurate fluid level measurement. By having the engine running, the fluid is circulated and maintained at its normal operating level, allowing for a precise reading.
Checking Procedure
To check the ATF level, follow these steps:
- Warm up the engine by driving the car for a few minutes.
- Park the car on level ground and engage the parking brake.
- Start the engine and move the gear shifter through all the positions, holding each for a few seconds.
- Use the transmission fluid dipstick to measure the fluid level.
