In 2010, the Civic offered both a 5-speed automatic and a 5-speed manual transmission. The fluid specifications depend on which transmission your car has. For most U.S.-market Civics of that year, the automatic uses Honda ATF-Z1, while the manual uses Honda Manual Transmission Fluid (MTF). Regional variations exist, so always verify with your owner's manual or dealer.
For quick reference: automatic transmissions in the 2010 Civic typically require Honda ATF-Z1 (with some regions approving DW-1), while the manual transmission requires Honda MTF tailored to Honda’s GL-4 specification. Check your manual for the exact requirement for your VIN and market.
Automatic transmission (5-speed automatic)
Overview paragraph: The Civic’s automatic transmission has a specific Honda-supplied fluid. Using the correct ATF is important for smooth shifting and transmission longevity.
- Fluid type: Honda Genuine Automatic Transmission Fluid ATF-Z1 is the standard specification for the 2010 Civic’s 5-speed automatic in many markets. In some regions, DW-1 may be specified or approved, so confirm for your vehicle.
- Compatibility note: Do not mix ATF types. Always use the exact fluid specified in your owner’s manual or by a Honda service advisor for your region.
- Service guidance: Follow the maintenance schedule in your manual for drain-and-fill intervals or flushing, as recommended by Honda for your specific model and market.
Concluding paragraph: The key message is to use the Honda-specified ATF (Z1, or DW-1 if your region lists it) and to follow the official service intervals to protect shifting performance and warranty.
Manual transmission (5-speed manual)
Overview paragraph: The manual transmission is filled with a different fluid than the automatic, tailored to manual transmission needs and gear engagement performance.
- Fluid type: Honda Genuine Manual Transmission Fluid (MTF) or an equivalent that meets Honda’s GL-4 specification as specified for the 2010 Civic manual transmission.
- Typical viscosity guidance: Many markets use a 75W-90 grade for the MTF, but the exact viscosity requirement can vary by region. Always confirm with the owner’s manual for your market.
- Service guidance: Use the recommended MTF and follow the maintenance intervals in your manual; avoid mixing with automatic transmission fluid.
Concluding paragraph: Using the correct MTF is essential for smooth gear engagement and long transmission life. Always reference the manual or a Honda dealer to confirm the proper fluid specification for your trim and region.
Summary
The 2010 Honda Civic's transmission fluid depends on the type of transmission installed. Automatic transmissions typically require Honda ATF-Z1 (with DW-1 approved in some regions), while manual transmissions require Honda MTF meeting GL-4 specifications. Regional differences can apply, so always check the owner’s manual or consult a dealer to confirm the exact fluid type and maintenance intervals for your VIN.
