Fluid Type Explained

The 2020 Chevrolet Malibu can come equipped with one of two main transmission types, each requiring a specific and non-interchangeable transmission fluid:

• Continuously Variable Transmission (CVT): Models with the 1.5L turbocharged engine typically feature a CVT. This transmission requires DEXRON ULV (Ultra Low Viscosity) fluid. This fluid is specially formulated for the unique demands of a CVT, providing excellent friction characteristics for the belt or chain, anti-wear properties, and thermal stability.

• 9T50 9-Speed Automatic Transmission: Models with the 2.0L turbocharged engine are generally paired with the 9T50 9-speed automatic transmission. This unit requires DEXRON HP (High Performance) fluid. DEXRON HP is designed to provide optimal shift quality, durability, and efficiency for modern multi-speed automatic transmissions.

Using the incorrect fluid in either of these transmissions can lead to severe damage, premature wear, and potential transmission failure. Always consult your owner's manual or a Chevrolet service technician to confirm the correct fluid for your specific vehicle.

Service Procedure

There are two primary methods for servicing transmission fluid:

• Drain & Fill: This method involves draining the old fluid from the transmission pan and refilling with new fluid. It's the most common procedure for routine maintenance and can be done by a competent DIYer or a professional. However, it only replaces a portion of the total transmission fluid, as a significant amount remains in the torque converter, valve body, and cooler lines. For the 2020 Malibu, a drain and fill will replace roughly half to two-thirds of the total fluid capacity.

• Full Exchange (Fluid Flush): A full exchange involves using specialized equipment to completely remove all old fluid from the transmission system and replace it entirely with new fluid. This method ensures all contaminants and worn-out additives are removed. While more thorough, it is also more involved and typically requires professional equipment. Some manufacturers advise against power flushing certain transmissions, so always consult your owner's manual or a certified Chevrolet technician before opting for a full exchange.

For models equipped with a replaceable filter, the transmission fluid filter should also be replaced during a fluid service. The location of the filter varies, but it is typically inside the transmission pan.

Service Interval

Maintaining the correct transmission fluid level and quality is crucial for the longevity and performance of your 2020 Chevrolet Malibu's transmission. The recommended service interval can vary based on driving conditions:

• Normal Duty: For vehicles driven under typical conditions (highway driving, minimal towing, moderate climate), Chevrolet recommends servicing the transmission fluid at 97,500 miles (150,000 km). This interval assumes the vehicle is not subjected to extreme stress.

• Severe Duty/Towing: If your Malibu is regularly subjected to severe driving conditions such as heavy city traffic, frequent short trips, prolonged idling, driving in hilly or mountainous terrain, or towing, the transmission fluid should be serviced more frequently. For these conditions, the recommended interval is significantly reduced to 45,000 miles (72,000 km). The increased heat and stress generated under severe conditions break down transmission fluid more quickly.

Regardless of the recommended intervals, it's good practice to periodically check your transmission fluid level and condition (color and smell). If the fluid appears dark, has a burnt smell, or if you notice any shifting anomalies, consider servicing the transmission sooner.
