How much transmission fluid does a 2017 Chevy Trax take?
A 2017 Chevy Trax with the 6-speed automatic typically requires about 11 quarts of Dexron VI transmission fluid for a full change. A basic drain-and-fill uses roughly 6–7 quarts, while a complete flush can approach 12 quarts depending on the method and equipment used.
Understanding the capacity and what affects it
The Trax uses a 6T40 automatic transmission. Service data generally lists a total system capacity of roughly 11 quarts, which covers the fluid needed for a full service that includes pan drop and filter replacement. The amount you actually refill can vary based on whether you replace the filter, whether you drain the torque converter, and whether you use a flush machine that circulates additional fluid through the system.
Fluid type and how to verify the level
Use Dexron VI automatic transmission fluid unless your owner's manual specifies otherwise. After completing the service, follow GM guidelines to check the level—typically with the engine at operating temperature and the transmission in Park—so the level sits within the recommended range on the dipstick or level indicator.
Practical steps for changing transmission fluid
Below is a broad outline of the typical steps and the quantities involved. The exact amounts depend on whether you replace the filter and whether you fully drain the torque converter.
- Warm the vehicle and safely lift it for access to the transmission pan.
- Drain the pan to remove old fluid; the amount drained is typically about 6–7 quarts in a standard drain-and-fill without removing the pan.
- Remove the pan, inspect and replace the filter if equipped, clean the pan and magnets, then reinstall with a new gasket.
- Refill with Dexron VI. Start with roughly 6 quarts, then run the vehicle through gears and check the level when hot, adding as needed to reach the full mark.
- Cycle the gears again, recheck, and top off to the specified level while avoiding overfill.
Note: This is a general guide. Always consult the GM service manual or a qualified technician for the exact procedure and quantities for your vehicle.
Summary
For a 2017 Chevy Trax (6T40 automatic), plan on about 11 quarts for a complete transmission fluid change, roughly 6–7 quarts for a drain-and-fill, and around 12 quarts if performing a full flush. Use Dexron VI and verify the level according to GM guidelines after the service.
