  5. Torque wrench, 3/8 or 1/2 in drive

The E210 Corolla has no transmission dipstick. Draining is easy; getting the level right is the whole job. On the 1.8 and 2.0 non-hybrid cars, the K120 Direct Shift-CVT uses a drain plug with an overflow tube inside it, so you refill through a side fill port, then run the engine until the fluid hits 40-45 C and let the excess spill out of the tube. Hybrids use a conventional eCVT transaxle where you simply put back exactly what you took out, with the car level.

The two things people get wrong: using the wrong fluid (CVT Fluid FE for the K120, ATF WS for the hybrid transaxle — they are not interchangeable), and setting the level with only the front of the car in the air. Also crack the fill plug loose before you touch the drain plug. A seized fill plug on a drained transaxle turns a two-hour job into a tow.

Partsshop
Toyota Genuine ATF WS
Hybrid P610/P710 transaxle — plan on 3-4 quarts
The hybrid transaxle takes ATF WS, not CVT FE; the two are not interchangeable.
Partsshop
Brake/parts cleaner and rags

Cleans the case around the plugs so you can spot leaks afterward.
Consumablesshop
Nitrile gloves and safety glasses

Hot fluid runs down your arm when the plug clears the threads.
Safetyshop
Funnel with flexible neck

Useful for pouring into the pump reservoir without spilling on the exhaust.

Differences within the 2020-2024 generation

The 1.8 L 2ZR-FAE and 2.0 L M20A-FKS both use the K120 CVT, so tools and fluid are identical between them: 24 mm outer plug, 6 mm hex overflow tube, Toyota CVT Fluid FE, and the warm-idle overflow level procedure. The hybrid's P610/P710 transaxle uses a 24 mm drain and 24 mm fill plug, Toyota ATF WS, a smaller refill quantity, and no overflow-tube level set. Manual-transmission Corolla hatchbacks (6MT) are a different job entirely, using 75W gear oil and a hex-head fill/drain.

How the job goes

  1. Drive the car 10-15 minutes so the fluid is warm and suspended, then park on level ground, chock the wheels and set the parking brake.
  2. Raise the front of the car and support it on jack stands so the vehicle sits LEVEL side to side and front to back. A tilted car gives a wrong level reading. Raising all four corners is best.
  3. Remove the engine undertray/splash shield (10 mm and 12 mm bolts plus plastic clips) to expose the bottom of the transaxle.
  4. Locate the plugs. On the K120 CVT the drain/overflow assembly is on the bottom of the pan (a 24 mm outer plug with a 6 mm hex overflow tube inside it) and the fill plug is on the side of the case. On the hybrid, there is a 24 mm drain plug low on the transaxle and a separate 24 mm fill plug higher on the case.
  5. Loosen and remove the FILL plug first. If you cannot get it out, stop — you will not be able to refill the transaxle.
  6. Place the drain pan and remove the 24 mm drain/overflow outer plug. Let it drain fully. Measure what comes out; that is your refill target.
  7. CVT only: with the outer plug off, you can also remove the inner 6 mm hex overflow tube if you want maximum drain, then reinstall it before refilling. Fit new crush washers.
  8. Reinstall the drain plug (and overflow tube) with new gaskets, torqued to spec.
  9. Pump new fluid into the fill port until it starts to back out. Non-hybrid: refill with the same amount you drained, roughly 3.5-4 L per drain and fill. Hybrid: refill the measured drained amount, typically about 2.5-3 L. Reinstall the fill plug.
  10. CVT level set: start the engine, shift slowly through P-R-N-D-N-R-P, then let it idle while monitoring transaxle fluid temperature with a scan tool (or the case with an IR thermometer) until it reaches 40-45 C / 104-113 F.
  11. With the engine still idling in Park and the fluid in that window, remove only the 24 mm outer plug and let excess fluid dribble out of the overflow tube. When it thins to a drip, install the outer plug with a new washer and torque it.
  12. Hybrid: no overflow procedure is needed if you refill the exact drained quantity with the vehicle level; refit the fill plug and torque it.
  13. Shut off the engine, clean the case with brake cleaner, refit the undertray, lower the car and test drive. Recheck for leaks and for any shift flare or shudder.
  14. Repeat the drain and fill in 500-1000 miles if the fluid came out very dark, to exchange more of the old fluid without dropping the pan.

Watch out

Plug sizes on the E210 follow standard Toyota practice (24 mm outer drain/overflow and fill plugs, 6 mm hex inner overflow tube on the K120 CVT), but plug locations and refill quantities vary between the K120 CVT and the hybrid P610/P710, so confirm the plug sizes, exact capacity and all torque values against the Toyota repair manual for your VIN before you start.

Frequently asked

How often should the transmission fluid be changed on a 2020-2024 Corolla?

Toyota lists the K120 CVT fluid as a lifetime fill with no normal-service interval, and only specifies inspection under special operating conditions. Most techs who work on these recommend a drain and fill every 50,000-60,000 miles, sooner if you tow, do heavy stop-and-go, or drive in extreme heat.

What fluid does the E210 Corolla CVT take?

Toyota Genuine CVT Fluid FE for the K120 Direct Shift-CVT in the 1.8 L and 2.0 L non-hybrid cars. The hybrid's eCVT transaxle takes Toyota Genuine ATF WS instead. Do not substitute a generic multi-vehicle CVT fluid.

How much fluid does a drain and fill take?

Expect roughly 3.5-4 litres (about 4 quarts) out of the K120 CVT and around 2.5-3 litres from the hybrid transaxle. Buy 5 quarts so you have enough to top off during the overflow level set, and always measure what came out.

Can I do this without a scan tool?

Yes on the hybrid, since you just replace the measured quantity with the car level. On the K120 CVT you need to know the fluid temperature for the overflow check; an infrared thermometer aimed at the transaxle case near the pan will get you close, but a scan tool reading the live fluid temperature PID is far more reliable.
