Transmission Fluid for the 2012 Chevy Malibu
The Short Answer
The 2012 Chevrolet Malibu's automatic transmissions are specified by General Motors for Dexron VI automatic transmission fluid (ATF). Dexron is GM's own fluid standard, and VI is the current version that replaced earlier grades such as Dexron III. Buy a fluid that is GM-licensed to the Dexron VI specification. The license is normally shown on the container.
Which Transmissions This Covers
The 2012 model year was the last year of the Malibu generation sold from 2008 to 2012. The 2013 Malibu is a different generation, so its fluid information should not be assumed to match. For 2012, the Malibu was generally offered with six-speed automatic transmissions from GM's Hydra-Matic family. The transmission depends on the engine:
2.4-liter four-cylinder: six-speed automatic, commonly identified as the 6T40 (also referred to as the 6T45 in related applications); 3.6-liter V6: six-speed automatic, commonly identified as the 6T70
Both gearboxes use Dexron VI, so the fluid type is the same whichever engine the car has. Fill capacity and service procedure can differ between the two. Earlier Malibus from this generation were also offered with a four-speed automatic, so a fluid recommendation for a 2008 or 2009 model is not automatically transferable.
Qualifications That Change the Answer
Fluid type: Dexron VI is the documented GM requirement. Using an older grade such as Dexron III where Dexron VI is specified is not recommended. "Multi-vehicle" or universal ATF: these products may claim Dexron VI suitability without holding a GM license. Whether they perform equivalently is a matter of manufacturer claims, not GM certification. Checking the level: the six-speed units in this Malibu are generally described as lacking a conventional dipstick. Level is typically checked through a check plug with the fluid at a specified temperature. Follow the service manual procedure rather than improvising. Capacity: no verified fill figures were available for this guide. Drain-and-refill amounts are usually well below total system capacity. Confirm the quantity in the owner's manual or a factory service source before purchasing.
What to Confirm Before Buying
Check the owner's manual or ask a Chevrolet dealer's parts department for your car's engine and transmission. Confirm the fluid specification, the service capacity and the level-check procedure. A dealer can look these up from the vehicle identification number (VIN). This guide does not include an independent fluid test or a brand comparison. Any choice between licensed Dexron VI products comes down to availability and price, not documented performance differences.
