In brief, the 2010 Honda Civic offered different transmissions depending on the trim: most gasoline models (LX, EX, EX-L) could be equipped with either a 5-speed manual or a 5-speed automatic; the Civic Si was manual-only with a 6-speed gearbox; and the Civic Hybrid used a CVT paired with Honda’s IMA hybrid system.
Gas-powered models: LX, EX, and EX-L
The following transmission options were available on the non-Si, gas-powered Civics for 2010. This applies to the LX, EX, and EX-L trims with the conventional gasoline engine.
- 5-speed manual transmission (5MT)
- 5-speed automatic transmission (5AT)
These two options gave buyers a choice between additional engagement and potential fuel-economy benefits from a manual, or the convenience and smoothness of an automatic. Availability could vary by market and specific model configuration.
Civic Si: performance-oriented model
The high-performance Si model was offered with a single transmission choice geared toward enthusiasts.
- 6-speed manual transmission (6MT)
The Si’s 6-speed manual is standard, emphasizing driver involvement and sportier driving dynamics compared with the other trims.
Civic Hybrid: IMA-equipped model
The 2010 Civic Hybrid utilized Honda’s Integrated Motor Assist system paired with a continuously variable transmission specific to the hybrid setup.
- Continuously variable transmission (CVT) associated with the IMA hybrid system
The hybrid transmission was designed to optimize efficiency by continuously adjusting gear ratios as needed, in conjunction with the electric motor assist.
Summary
Across the 2010 Honda Civic lineup, transmission options varied by trim: LX/EX/EX-L offered either a 5-speed manual or a 5-speed automatic, the Si came with a 6-speed manual, and the Civic Hybrid used a CVT tied to Honda’s IMA system. Buyers chose based on preference for driving feel or fuel efficiency, with the Si remaining the enthusiast choice and the Hybrid prioritizing efficiency.
