In a nutshell, a 2005 Honda Civic offered multiple transmission options depending on the trim: a 5-speed manual, a 4-speed automatic, a 6-speed manual for the Civic Si, and a CVT for the Civic Hybrid.
The 2005 Civic lineup included several versions with distinct gearbox configurations. Below is a breakdown by major model family to help you identify which transmission your car might have or which to look for when shopping or researching maintenance.
Non-hybrid Civics (DX/LX/EX)
For most non-hybrid Civics in 2005, buyers could choose between a traditional manual gearbox or an automatic, with the exact option depending on the trim.
- 5-speed manual transmission (5MT) — common on many non-hybrid trims
- 4-speed automatic transmission (4AT) — offered on other trims
In practice, if you own a 2005 Civic that isn’t a hybrid or Si, you are likely dealing with one of these two gearbox types.
Civic Si (high-performance version)
The 2005 Civic Si, aimed at performance enthusiasts, was equipped with a 6-speed manual transmission.
- 6-speed manual transmission
That year’s Si model traded the older five-speed in favor of a six-speed setup to optimize power delivery and driving experience.
Civic Hybrid (2005 Hybrid model)
The Civic Hybrid used Honda’s Integrated Motor Assist (IMA) system paired with a continuously variable transmission, commonly referred to as an automatic CVT or e-CVT.
- CVT (continuously variable transmission) — e-CVT with IMA
This arrangement prioritizes smooth acceleration and fuel efficiency over a traditional stepped-gear feel.
Summary
To recap, the transmission options for a 2005 Honda Civic vary by model: non-hybrid Civics typically offered a 5-speed manual or a 4-speed automatic; the Civic Si featured a 6-speed manual; and the Civic Hybrid used a CVT paired with Honda’s IMA hybrid system. When evaluating a specific car, check the trim badge or VIN to confirm the exact gearbox configuration.
