The quick answer depends on the transmission. For most 2009 Civics with the 5-speed automatic, the total capacity is about 7.0–7.5 quarts of ATF. For the 5-speed manual, the capacity is about 1.8–2.0 quarts. Note that the Civic Si (6-speed manual) uses a different, higher capacity and is not covered by these figures; check the owner's manual for that model.
Two common transmissions in the 2009 Civic
These are the configurations most owners encounter in US-market Civics from that year; capacities differ between automatics and manuals.
Automatic transmission (5-speed)
Capacity figures for the 5-speed automatic are typically quoted as a total fill of about 7.0–7.5 quarts, depending on whether a new filter is installed. A drain-and-fill (pan drain only) generally replaces around 4–5 quarts, since some fluid remains in the torque converter and passages. Use Honda ATF DW-1 (or an equivalent approved by Honda) when servicing.
- Total capacity: ~7.0–7.5 quarts
- Drain-and-fill (pan drain only): ~4–5 quarts
- Fluid type: Honda ATF DW-1 or equivalent
- Filter change: Adds capacity to the total fill when a new filter is installed
In short, plan for around seven quarts if replacing all fluid with a full fluid change; a standard drain-and-fill will move roughly four to five quarts of fluid.
Manual transmission (5-speed)
The 5-speed manual in most 2009 Civics holds a smaller amount of fluid. The approximate capacity is about 1.8–2.0 quarts, depending on the exact transmission casting and model sub-variant. Use the manual transmission fluid specified in the owner's manual (often Honda MTF) and ensure the level is within the recommended range after filling.
- Capacity: ~1.8–2.0 quarts
- Fluid type: Honda MTF or equivalent per owner's manual
- Notes: Minor variations can occur between trims
For a complete drain-and-fill, expect to use about two quarts of fluid.
Notes on variants and verification
Capacities vary slightly by body style (sedan vs. coupe), trim, and whether you’re dealing with the Civic Si or other special variants. Always confirm the exact specification in the owner's manual or Honda service bulletin for your vehicle’s VIN and transmission type before purchasing fluid.
Summary
Summary: The most common 2009 Honda Civic automatic transmission takes roughly 7 quarts in total, with a drain-and-fill around 4–5 quarts. The 5-speed manual uses about 1.8–2.0 quarts. If you own a Civic Si or a non-standard trim, consult the manual for the precise figure. When in doubt, perform a careful drain-and-fill and check the level according to the service procedure.
