How to Check Transmission Oil on a 2001 Toyota Corolla

Updated February 21, 2017

The 2001 Toyota Corolla has an automatic transmission installed. The automatic transmission changes gears as the vehicle operates without the driver having to manually change gears. To ensure the transmission runs properly and smoothly, automatic transmission fluid is used to lubricate the gears and components within the transmission. It's important to check the transmission level anytime the regular motor oil is checked. Low transmission fluid levels can cause damage to the transmission and cause the Corolla to not run efficiently.

Drive the 2001 Corolla for 10 minutes to ensure the transmission fluid is at operating temperature for an accurate measurement. Place the vehicle in "park" on a level surface.

Open the bonnet of the Corolla and find the automatic transmission fluid reservoir. Look for the dipstick that is coloured red and labelled "ATF." In the 2001 Corolla, the ATF is located on the driver side of the vehicle, opposite of the motor oil reservoir and dipstick.

Remove the dipstick from the reservoir by pulling it out. Wipe the dipstick clean with a rag and replace it. Remove the dipstick once more. Read the fluid measurement, the fluid should fall somewhere between "add" and "full." If the measurement is below the "add" line, it's imperative to add fluid immediately.

Insert a funnel into the reservoir neck. Pour the appropriate amount of automatic transmission fluid slowly into the funnel. Once all fluid has entered the reservoir, check the levels again. If needed, continue to add fluid until the measurement reaches "full." Once finished, close the bonnet of the Corolla.
