For a 2010 Honda Civic, the correct fluid depends on the transmission. The automatic transmission uses Honda ATF DW-1, while the 5-speed manual uses Honda Genuine Manual Transmission Fluid (MTF). Always verify your exact transmission type in the owner's manual or on the vehicle’s door jamb label if you’re unsure.
Two transmissions, two fluids
The 2010 Civic was offered with either a 5-speed manual or a 5-speed automatic transmission. Fluid specifications differ between these two setups, and using the wrong fluid can lead to shifting issues or wear over time. The guidance below reflects Honda’s official recommendations for these two configurations.
Fluid recommendations by transmission type
Below are the official fluids typically specified by Honda for the 2010 Civic, broken down by transmission type. Each list shows the primary recommended fluid and notes any important considerations.
Automatic transmission (5-speed)
Before listing the recommended fluid, it’s important to know that the automatic transmission in the 2010 Civic uses Honda’s ATF DW-1. This fluid is formulated to meet the needs of Honda automatics and is the factory-recommended fluid for this transmission.
- Honda ATF DW-1 (Honda Genuine Automatic Transmission Fluid, DW-1 specification)
Bottom line: Use Honda ATF DW-1 for the automatic transmission. Do not substitute other ATFs unless explicitly approved by Honda, and follow the recommended service interval in your owner’s manual.
Manual transmission (5-speed)
The 2010 Civic’s manual transmission requires Honda Genuine Manual Transmission Fluid (MTF). For best results, use MTF that meets API GL-4 specification. Avoid GL-5 gear oils, as they can be harsh on synchronizers and other manual-transmission components.
- Honda Genuine Manual Transmission Fluid (MTF) meeting API GL-4
Bottom line: Use MTF (GL-4) designed for Honda manual transmissions. If MTF is unavailable, a GL-4 gear oil with the correct viscosity may be used as a substitute per manufacturer guidance, but confirm compatibility with your transmission before proceeding.
Summary
For a 2010 Honda Civic, the fluid choice hinges on the transmission type. Automatic transmissions use Honda ATF DW-1, while 5-speed manual transmissions use Honda Genuine MTF that meets API GL-4. Always verify the specific transmission in your car’s documentation and avoid mixing fluids. Following the correct fluid and service intervals helps ensure smooth shifting and long transmission life.
