How much gear oil does a Chevy Cruze automatic transmission hold?
The Cruze’s automatic transmission typically holds about 9 to 10 quarts of Dexron VI automatic transmission fluid (ATF) when filled to spec. A standard drain-and-fill service usually replaces about 4 quarts. The exact amount depends on model year and the specific transmission variant used in the car.
In this article we break down the numbers, explain why they vary across Cruze generations, and offer practical guidance for checking and refilling ATF safely and accurately.
Typical capacity figures
These figures provide a practical reference for Cruze models that use GM’s 6-speed automatic transmissions.
- Total system capacity (including torque converter): about 9.0 to 10.0 quarts (roughly 8.5 to 9.5 liters).
- Drain-and-fill replacement (partial change): about 4.0 to 5.0 quarts (roughly 3.8 to 4.7 liters).
- Fluid specification: Dexron VI (or Dexron VI–compatible) automatic transmission fluid.
In practice, plan for roughly a full refill of about 9 to 10 quarts if you are performing a complete fluid change, while a single drain-and-fill will typically swap out around 4 quarts. Always confirm with your vehicle’s service data for the exact figures applicable to your VIN.
Model-year and variant nuances
Different Cruze generations and markets have used slightly different transmission configurations. Here is a general guide to what owners may encounter.
- 2011–2015 Cruze with the 6T40/6T30 automatic: total capacity around 9.5 quarts; drain-and-fill around 4–5 quarts; Dexron VI ATF recommended.
- 2016–2019 Cruze (primarily with the 6T40): similar overall capacity, with typical drain-fill in the 4–5 quart range; some markets may list minor variations or use closely related 6-speed units.
- Note: Some markets or trims may reference alternate GM transmissions; the general guidance remains similar, but always verify with the official service data for your exact transmission and VIN.
Because capacities can differ by year and by the precise transmission model, the best practice is to consult the owner’s manual or GM service data for your Cruze’s VIN before buying fluid or starting a change.
Practical tips for maintenance
Choosing the right fluid
Use Dexron VI ATF or a fluid labeled Dexron VI-compatible. Using the wrong fluid can affect shifting performance and longevity.
How to check and refill safely
Follow the service manual for your exact transmission and vehicle. Some Cruzes have dipsticks for ATF levels, while others use a temperature-based fill method. Always check the fluid at the correct temperature and after a proper drain-and-fill sequence to ensure accurate level readings.
Summary
For most Chevy Cruzes with the common 6-speed automatic, you’re looking at a total capacity of roughly 9–10 quarts of ATF, with about 4 quarts replaced during a standard drain-and-fill. Dexron VI ATF is the standard specification. Because capacities can vary by year and transmission type, verify the exact figure for your VIN in the owner’s manual or GM service data, and consider professional service if you’re unsure about the procedure.
