Short answer: It varies by trim — non-Si Civics offered a 5-speed manual or a 5-speed automatic, the Civic Si used a 6-speed manual, and the Civic Hybrid used an electronic CVT (e-CVT).
Overview of transmissions in the 2012 Civic
In 2012, Honda offered three main transmission setups across the Civic lineup depending on model and powertrain. Here is how they break down by trim.
Non-Si Civics (LX, EX, EX-L)
Non-Si Civics were available with two conventional transmissions: a traditional 5-speed manual or a 5-speed automatic. This applied to most gas-powered trims in the U.S. market for that model year.
- 5-speed manual transmission
- 5-speed automatic transmission
For buyers, the choice between manual and automatic affected driving feel and fuel economy, with the automatic offering smoother operation in city driving.
Civic Si
The performance-oriented Si used a single drivetrain configuration focused on sportier driving: a 6-speed manual transmission only.
- 6-speed manual transmission
The Si did not offer an automatic option in 2012, consolidating its manual gearbox as part of its sporty character.
Civic Hybrid
The 2012 Civic Hybrid employed Honda's hybrid powertrain paired with an electronic CVT-style transmission designed for efficiency.
- e-CVT (electronic CVT)
As with most hybrids, this transmission prioritizes smooth power delivery and fuel efficiency rather than traditional step ratios.
Summary
The 2012 Honda Civic lineup offered a mix of manuals, automatics, and a hybrid e-CVT, with the Si relying on a 6-speed manual, non-Si gas models offering 5-speed options, and the Hybrid using an electronic CVT for efficiency.
