How often should the Punch CVT transmission fluid be changed?
2 Answers
Generally, the transmission fluid for CVT transmissions needs to be replaced every two years or every 40,000 kilometers under normal circumstances (referred to as ATF). However, this varies depending on the vehicle model, as different models have different requirements. For Japanese car models, it is recommended to change the fluid every 40,000 to 60,000 kilometers. Vehicles that frequently drive at high speeds are advised to change the fluid approximately every 40,000 kilometers. More relevant information is as follows: 1. Introduction to Transmission Fluid: Transmission fluid, commonly known as gear oil, is used within the transmission and serves as a cleaning product for the transmission system. Transmission fluid is divided into automatic transmission fluid (ATF) and manual transmission fluid (MTF). ATF is specifically designed for automatic transmissions, while MTF is for manual transmissions. The quality of transmission fluid directly affects the transmission's operational performance. 2. Functions of Transmission Fluid: Transmission fluid provides lubrication, cleaning, rust prevention, heat dissipation, and gear shifting functions. During driving, gears operate at high speeds, generating heat through friction, which requires transmission fluid for lubrication and temperature reduction to ensure the vehicle's normal operation. It also helps reduce fluid loss under harsh operating conditions.
The recommended replacement interval for this Punch CVT transmission fluid is typically every 60,000 to 80,000 kilometers, depending on the manufacturer's manual. Having driven a CVT vehicle myself, I've observed that its transmission relies on fluid for power transfer and pressure regulation. Degraded fluid can lead to slippage or noise issues. Once, I delayed the change until 90,000 kilometers, and afterward, the transmission developed some abnormal sounds, resulting in higher repair costs later. Therefore, regular replacement helps prevent major failures, especially in urban stop-and-go traffic where fluid temperatures rise easily, accelerating fluid degradation. I suggest inspecting the fluid condition every two years or 60,000 kilometers to avoid unnecessary troubles. Neglecting replacement not only damages components but may also affect driving smoothness. Developing this maintenance habit saves both hassle and money in the long run.
