For most 2013 Civics with the standard 5-speed automatic transmission, the total fluid capacity is about 9.5 quarts (roughly 9.0 liters). For manual transmissions, the capacity is around 2.4–2.6 quarts (about 2.3 liters).
The exact amount depends on the specific transmission in your trim, and on whether you are performing a drain-and-fill or a complete fluid flush. A drain-and-fill replaces fewer quarts than the total capacity, while a full flush will approach the full specification. Always verify with the owner's manual or a trusted service guide for your exact configuration.
Transmission fluid capacity by transmission type
The following figures reflect typical capacities listed in Honda service data. Use them as a baseline, and confirm with the manual for your exact trim.
- Automatic (5-speed automatic): total capacity about 9.5 quarts (9.0 L). If you drain and refill without replacing the filter, you may replace around 6–7 quarts; if you replace the filter as well, plan for roughly 9–10 quarts.
- Manual (5-speed, non-Si): capacity about 2.4–2.6 quarts (approximately 2.3 L).
- Manual (Si, 6-speed): capacity around 2.5–2.7 quarts (about 2.4 L).
These figures are guidelines. For exact capacity, refer to the owner's manual or Honda service data. The recommended fluids typically are Honda ATF DW-1 for automatic transmissions and the appropriate manual transmission fluid (MTF) for manuals.
What to consider when changing or flushing
When planning a transmission fluid service, keep in mind that fluid type and process matter as much as total capacity. The following checklist helps ensure you use the correct fluid and procedures.
- Use the specified fluid: Honda ATF DW-1 for most 2013 Civics with automatic transmissions; follow the manual's guidance for manuals.
- Warm up the transmission to operating temperature before draining to maximize fluid drainage.
- Check whether a filter service is required or available for your automatic transmission, as this affects total quarts needed.
- Fill to the correct level using the proper dipstick procedure or service bulletin; avoid overfilling, which can cause shifting issues.
- If you’re unsure about the exact specification for your trim, consult the owner’s manual or a Honda service tech.
Following the correct fluid type and capacity guidance helps protect the transmission and maintain smooth shifting. If you’re not confident performing the service yourself, a qualified technician can handle the fill accurately.
Summary
In short, the 2013 Civic’s transmission fluid capacity varies by transmission type: about 9.5 quarts (9.0 L) for automatic transmissions and about 2.4–2.6 quarts (2.3 L) for manuals. Always verify exact figures in the owner's manual for your specific trim and service type (drain-and-fill vs. flush), and use the recommended Honda fluids for best results.
