How Often Should Toyota Transmission Fluid Be Changed?
2 Answers
Toyota transmission fluid should be changed every 2 years or 40,000 kilometers. Transmission fluid is an oil product that maintains the cleanliness of the gear system, ensuring the proper functioning of the transmission and extending the lifespan of the transmission components. Over time, transmission fluid deteriorates and evaporates under high-speed and high-temperature conditions, which can accelerate the wear of mechanical parts and, in severe cases, damage internal transmission components. Taking the 2021 Toyota Corolla TNGA 1.5L Manual Pioneer Edition as an example: its engine has a maximum power output of 89 kilowatts, utilizes front-wheel drive, features a front MacPherson independent suspension, and employs an E-type multi-link independent suspension at the rear.
Attention Toyota owners! Transmission fluid really shouldn't be left unchanged forever. My Camry technician said during last maintenance that regular automatic transmission Toyotas used for city commuting should have fluid changed every 60,000 to 80,000 km. For frequent highway driving or aggressive driving styles, it's recommended to check fluid condition around 50,000 km. My old RAV4 went 100,000 km without a change, and shifting became noticeably jerky - the mechanic said the fluid was as black as soy sauce. I've learned my lesson now - even though the maintenance manual says Corolla CVT transmissions need fluid changes at 40,000 km, I get it done 5,000 km early. After all, transmission repairs cost way more than fluid changes.
