The 2012 Chevrolet Cruze uses Dexron VI automatic transmission fluid (ATF) for automatics and a GL-4 75W-90 gear oil for manuals. The exact fluid depends on your car’s transmission type and code, so confirm with your manual or dealer if you’re unsure.
Transmission types in the 2012 Cruze
Chevrolet offered two primary transmission options for the 2012 Cruze. The fluid requirements differ between automatic and manual gearboxes.
- Automatic transmission (GM 6T40 family): Dexron VI automatic transmission fluid. This is the recommended standard for 6T40-based automatics and is backward-compatible with older Dexron specifications; Dexron III is not preferred for new fills.
- Manual transmission (Getrag-based): High-quality gear oil, typically 75W-90, meeting API GL-4 specification. Always verify the exact specification in the owner’s manual for your specific model/year.
In summary, automatics use Dexron VI ATF, while manuals use GL-4 75W-90 gear oil. Always double-check your vehicle’s manual or VIN-specific GM guidance to ensure the correct fluid and fill amount.
Where to verify the exact specification
Your best source is the owner’s manual or a Chevrolet dealer service bulletin for your vehicle’s transmission code. If you don’t have the manual, a dealer service advisor or a GM-certified repair shop can confirm the precise fluid specification for your Cruze based on its transmission type and VIN.
Maintenance tips for reliability
- Don’t mix ATF types; use Dexron VI for automatics. - Do not use ATF in a manual transmission or gear oil in an automatic. - Change intervals vary by driving conditions; follow GM’s service schedule and inspect for leaks or shifting concerns during service visits.
Summary
The 2012 Chevy Cruze requires Dexron VI ATF for automatic transmissions and GL-4 75W-90 gear oil for manual transmissions. Confirm your specific transmission type and consult the owner’s manual or a dealer to ensure you use the correct fluid and fill according to GM’s guidelines.
