The Cruze’s automatic transmissions typically require Dexron VI automatic transmission fluid, while manual transmissions use a GL-4 75W-90 gear oil. Always confirm with your owner’s manual or the transmission label for your exact year and model.
Automatic transmissions in the Chevy Cruze
Most Cruze models manufactured with an automatic transmission use GM Dexron VI ATF. The Cruze has commonly employed 6-speed automatic gearsets in the 6T40/6T45 family, and Dexron VI is the standard specification recommended by GM for these units. Dexron VI is designed to be backward compatible with older Dexron types, but the recommended fluid is Dexron VI for best shifting and longevity.
Note: Transmission fluid requirements can vary slightly by year and market, so it’s important to verify the exact specification listed in your owner’s manual or on the transmission’s dipstick label if present.
Before you check or replace the fluid, the following notes summarize the typical guidance for Cruze automatics:
- Use Dexron VI automatic transmission fluid (ATF) as specified by GM for most Cruze automatics.
- Avoid mixing fluids outside the Dexron family unless GM explicitly approves it for your unit.
- Follow the service intervals recommended in your owner's manual to maintain shifting performance and transmission life.
Concluding: For Cruze automatics, Dexron VI ATF is the recommended fluid. Always refer to the owner’s manual for your specific model/year to confirm the exact specification and any region-specific guidance.
Manual transmissions in the Chevy Cruze
Some Cruze models are equipped with a 5-speed manual transmission and require a dedicated gear oil rather than automatic transmission fluid. The typical specification for GM manuals is a GL-4 rated gear oil, commonly a 75W-90 viscosity, to protect synchronizers and gears in these manual transmissions.
Before the list: the following outlines the standard manual transmission lubrication guidance often cited for Cruze models.
- Gear oil: GL-4 75W-90 (not GL-5) for the manual transmission. This specification helps protect the synchronizers and gears under normal driving and shift conditions.
Concluding: Do not use ATF in the manual transmission. Use a GL-4 75W-90 gear oil per your manual or dealer guidance, and verify with the exact spec for your VIN.
Summary
In short, the Chevy Cruze typically takes Dexron VI automatic transmission fluid for automatic transmissions, while manual transmissions use a GL-4 75W-90 gear oil. Always verify with your specific year and VIN against the owner's manual or the under-hood transmission label, as there can be variations by production year and market. Regular maintenance with the correct fluid helps ensure smooth shifting and extended transmission life.
