The 2011 Honda Civic’s transmission fluid capacity depends on the transmission type: about 9 quarts for the 5-speed automatic and about 2.3 quarts for the 5-speed manual.
The Civic offered two transmissions in 2011, and capacity figures refer to total system fill. For service work, you’ll typically replace only part of that amount, depending on whether you drain-and-fill or perform a complete flush, and you should use the recommended fluid for each transmission.
Transmission options for the 2011 Civic
Honda provided two main transmissions for the 2011 Civic. Knowing which one you have is essential to estimating the correct fluid quantity.
- 5-speed automatic (5AT): total transmission fluid capacity is about 9 quarts.
- 5-speed manual (5MT): transmission fluid capacity is about 2.3 quarts.
In practice, the numbers above refer to the full-fill capacity of the respective transmission. For service work, the amount you remove and replace will vary: typically around 3–4 quarts for an automatic drain-and-fill, and roughly 1.5–2 quarts for a manual drain-and-fill. Always use the recommended fluid type for your transmission (Honda DW-1 for automatics; the appropriate manual transmission fluid per the owner's manual).
Maintenance considerations: how this affects servicing
When planning a transmission fluid change, distinguish between a simple drain-and-fill and a full flush. A drain-and-fill replaces only a portion of the total capacity, while a flush attempts to replace nearly all of the old fluid. The exact quantities depend on the service procedure and vehicle condition.
Summary
For a 2011 Honda Civic, the total transmission fluid capacity is roughly 9 quarts for the automatic and about 2.3 quarts for the manual. The amount you need to service your transmission will depend on whether you’re performing a drain-and-fill or a full flush, and you should always follow the fluid specifications listed in the owner's manual for your specific VIN and transmission type.
