For a 2009 Honda Civic, the transmission fluid capacity varies by transmission type: automatic transmissions typically require about 12 quarts in total, while manual transmissions hold roughly 2.5 quarts. If you’re doing a simple drain-and-fill, expect to replace around 4 quarts for the automatic and about 2 quarts for the manual.
The 2009 Civic offered two transmission options: a 5-speed automatic and a 5-speed manual. Capacities can differ slightly based on the exact model and service method (pan drop vs. full flush). The figures below reflect common guidance used by owners and service manuals.
Automatic transmission
Before listing the figures, keep in mind that the numbers assume standard service practices (such as a pan drain and refill or a full transmission flush). Actual values can vary a bit by model and maintenance history.
- Total capacity (with filter): about 12 quarts (roughly 11–12 quarts range is often cited in guides).
- Pan drain capacity (fluid removed during a typical pan drop): about 3.5–4.5 quarts.
- Drain-and-fill amount (to complete a pan-only service): roughly 4–5 quarts to bring the system back toward full, then check and top off as needed.
- Full system flush/replacement: can require around 12 quarts to completely replace fluid throughout the transmission.
Note: Exact numbers depend on whether you replace the filter, the procedure used, and the specific Civic trim. Always verify with the owner's manual or a trusted service source for your vehicle.
Manual transmission
Manual transmissions in the 2009 Civic require far less fluid, and capacities are typically more consistent across trims. The figures below reflect common practice for the manual gearbox used in that year.
- Total capacity: about 2.4–2.7 quarts.
- Drain-and-fill amount (typical): about 2.0–2.3 quarts to replace the drained fluid and reach proper level.
- Top-off considerations: after a drain, you may need a small additional amount (a few tenths of a quart) to reach the correct dipstick level depending on how much fluid was drained.
As with the automatic, use the correct manual transmission fluid specification recommended by Honda for your model year, and consult the service manual or a dealership if you’re unsure about the exact quantity or procedure.
Summary
In practical terms, a 2009 Honda Civic’s automatic transmission holds roughly 12 quarts in total, with a typical drain-and-fill replacing about 4–5 quarts. The manual transmission holds about 2.5 quarts total, with a drain-and-fill typically replacing around 2 quarts. For any maintenance, confirm exact figures against your owner’s manual or a Honda service bulletin, and use the appropriate transmission fluid type specified by Honda.
