What brand of transmission oil does the Corolla use?

[Bethany]

Corolla uses Toyota Genuine ATF WS transmission oil. Symptoms of not changing the transmission oil include: 1. Decreased power - the vehicle responds sluggishly during acceleration with noticeable engine noise but no corresponding speed increase; 2. Difficult starts - at low gears, the engine revs up when accelerating but the vehicle covers less distance; 3. Transmission damage - overheating may occur, damaging bearings and gears; 4. Gearshift issues - jerky shifting, rough transitions, and unusual noises from the transmission. The transmission consists of gear transmission mechanisms and control mechanisms, whose function is to alter the speed and torque from the engine, either fixing or changing the gear ratio between the output and input shafts.

My Corolla just had its transmission fluid replaced. The manufacturer actually recommends Toyota Genuine ATF WS Automatic Transmission Fluid. This blue specialty oil is the best fit for the Corolla's CVT transmission, offering exceptional lubrication. During my last service at the dealership, the technician told me that this fluid effectively prevents transmission slippage and extends its service life. Of course, third-party brands aren't unusable either—options like Mobil's ATF3309 or Aisin's AFW6 also meet the standards. I'd recommend following the maintenance manual and changing the fluid every 40,000 kilometers for safety, since transmission repairs certainly don't come cheap.

I have a lot to say about changing transmission fluid. My old Corolla has run 150,000 kilometers. Genuine Toyota fluid is definitely the best match, especially for CVT models which require low-viscosity oil. Once a repair shop recommended Shell's Spirax S6 to me, and it worked quite smoothly, but the mechanic reminded me to make sure it meets the WS standard. Manual transmission models are much simpler, just use 75W-90 gear oil. Remember not to cheap out and buy no-name brands—repairing a damaged transmission could cost you ten times the price of fluid changes. Currently, a one-liter bottle of genuine fluid costs around 100 yuan, and a full fluid change including labor is about 500 yuan.

When it comes to transmission fluid, it's crucial to use the correct specification. For a Corolla automatic transmission, Toyota Genuine ATF WS is the safest choice. During my last maintenance, I specifically observed the 4S shop's operation - they directly pumped the OEM fluid from large metal drums. If purchasing yourself, Idemitsu ATF or Copton's CVT-specific fluid are also good options. The key is to avoid mixing different brands, as their additives may conflict. My neighbor experienced transmission jerking due to using off-brand fluid, ultimately costing thousands in repairs. The manual recommends changing fluid every 40,000-60,000 km, or earlier for severe driving conditions.
