Is the Highlander's Transmission AT or CVT?
2 Answers
The Highlander's transmission is a 6-speed automatic with manual mode, and it is a hydraulic AT transmission, not a CVT continuously variable transmission. The characteristics and maintenance methods of the two are as follows: Characteristics of the two: CVT has significant advantages in reliability and fuel economy due to its simple structure and lighter weight. On the other hand, AT transmissions perform more prominently in driving enjoyment and low-torque performance. However, due to cost and the complexity of mechanical manufacturing, AT transmissions are slightly less economical compared to CVTs. Transmission maintenance: Manual transmissions use mineral gear oil, which needs to be replaced every 3 years or 60,000 kilometers. If synthetic oil is used, the transmission oil should be regularly inspected, and as long as the oil quality is good, it can continue to be used without replacement. For automatic transmission models, most brands recommend replacing the transmission oil every 4 years or 60,000-80,000 kilometers. Due to its simple structure and the use of synthetic transmission oil, CVT transmissions have a longer replacement interval than automatic transmissions, with 80,000-100,000 kilometers being more appropriate. Since dual-clutch transmissions come in dry and wet types, their maintenance methods differ. Dry dual-clutch transmissions do not require oil changes, while wet dual-clutch transmissions need to have their transmission oil and filter replaced every 60,000 kilometers, similar to automatic transmissions.
As an experienced driver who has driven several cars, I understand that the Highlander uses a traditional automatic transmission, specifically an AT transmission. It's not the CVT type of continuously variable transmission. Toyota has good reasons for equipping the Highlander with an AT, as SUVs require reliability and adaptability to various road conditions. AT transmissions perform consistently when climbing hills or hauling heavy loads, with smooth and comfortable gear shifts. I've driven a friend's Highlander, and the 8-speed AT accelerates quickly without any lag in city or highway driving. For long-term use, it's recommended to change the transmission fluid regularly and check the fluid level every 40,000 kilometers to extend its lifespan. The chances of transmission issues are low, but avoid aggressive driving during summer overheating. Overall, the AT is well-matched with the Highlander, offering high durability and a worry-free driving experience.
