The steps to check the automatic transmission fluid of Nissan March are as follows:
First, shift the gear to P, start the engine, and keep it idling for 2 minutes.
Next, press the brake pedal and switch the gears in the following order: R-N twice, and N-D twice; keep pressing the brake pedal throughout the process, and finally shift to N. You can assess the fluid level by observing the marks on the transmission dipstick, where the normal fluid level should be between the high and low marks. The transmission's function is to change the transmission ratio and direction of motion, located between the clutch and central drive.
The standard procedure for checking transmission fluid includes parking the vehicle on a level surface, lifting the vehicle, and removing the transmission underplate.
Prepare a container to catch the fluid, connect a diagnostic computer to read the transmission temperature, start the vehicle to let it idle, and check the fluid level directly with the transmission dipstick.
After starting the vehicle, pull out the dipstick to check the reading, which should be between the highest and lowest marks.
After adjusting and filling the hydraulic fluid, a test run is required to recheck if the automatic transmission hydraulic fluid level is normal, and to confirm that there are no leaks from the oil pan, pipe joints, etc.
