[Scarlett]

The 9AT transmission in the Avancier is a ZF transmission, which is currently widely used in Buick and Chevrolet models under General Motors. It delivers excellent performance and ensures stable power output for the vehicle. Transmission maintenance methods: Regularly check the automatic transmission fluid level: Unlike engine oil, which is checked when the engine is cold, automatic transmission fluid should be preheated to approximately 50°C. Then, shift the gear lever through each position for 2 seconds before placing it in the parking gear. At this point, the normal fluid level on the dipstick should be between the maximum and minimum lines. Add automatic transmission protectant to the transmission: The recommended ratio is 5%. For older vehicles, it is advisable to add a bottle of automatic transmission leak stopper to restore aging transmission seals and prevent leaks. Understand the replacement cycle for automatic transmission fluid: Generally, the replacement cycle is 2 years or 40,000–60,000 kilometers. During normal use, the operating temperature of automatic transmission fluid is around 120°C, so it is essential to use high-quality transmission fluid.
