What brand of transmission oil does the Corolla use?
2 Answers
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.
