In brief, the automatic transmission in a 2004 Honda Accord typically holds about 11.5 to 12 quarts of ATF, while the manual transmission holds roughly 1.8 to 2.0 quarts of gear oil.
The 2004 Accord offered both automatic and manual transmissions, and the exact capacity depends on the drivetrain and the service method (full flush vs. drain-and-fill). The figures below reflect common configurations and standard maintenance practices, but always verify against your car’s manual or a Honda service bulletin for your specific VIN.
Transmission fluid capacity by type
The following figures summarize total capacities and typical service volumes for the two main transmission types found in the 2004 Accord.
- Automatic transmission (typical total capacity): about 11.5–12 quarts (11–11.5 L) of ATF, including the torque converter.
- Manual transmission (gear oil): about 1.8–2.0 quarts (1.7–1.9 L) of axle/gear oil, depending on model and lubrication fill procedure.
These figures reflect factory specifications and common service data. Real-world capacity can vary slightly by sub-model, production date, and whether the fluid includes a filter change.
Practical service guidance
When servicing the transmission, mechanics typically perform either a drain-and-fill or a full flush. The volumes below reflect typical practice for a 2004 Accord automatic transmission.
Drain-and-fill (automatic transmission)
Before listing the typical amount swapped in a drain-and-fill, note that this is a partial replacement that affects only the pan drainage and does not purge all fluid from the torque converter.
- Typical replacement volume: about 4–5 quarts (3.8–4.7 L) per drain-and-fill.
- Frequency: many owners perform this every 30,000–60,000 miles as part of routine maintenance; multiple cycles can improve overall fluid replacement over time.
Conclusion: A drain-and-fill is convenient and commonly recommended, but it does not change the entire fluid in the system in a single pass.
Full transmission flush
A full flush replaces most or all of the ATF, depending on the equipment and procedure used, and can yield a more complete refresh than a simple drain-and-fill.
- Typical total consumption to fully refill: about 10–12 quarts (9.5–11.4 L).
- Notes: Some flushing systems require slightly more or less; after the procedure, check the level as specified in the service manual and road-test the vehicle to ensure proper shifting.
Conclusion: A flush is more thorough but usually more expensive and should be done by a qualified technician, especially on older vehicles with service history gaps.
Summary
For a 2004 Honda Accord, expect roughly 11.5–12 quarts of ATF in the automatic transmission and about 1.8–2.0 quarts of gear oil in the manual transmission. The exact amount you drain, fill, or flush depends on the service method and whether you’re changing only fluid or also the filter or pan gasket. Always confirm with your owner’s manual or a Honda service bulletin for your exact configuration.
