The 2015 Honda Civic primarily uses a continuously variable transmission (CVT) automatic for most trims, while the high-performance Civic Si uses a 6-speed manual transmission.
In the 2015 model year, Honda offered two main transmission setups for the Civic lineup: a CVT automatic for fuel efficiency and smooth acceleration, and a traditional manual gearbox for enthusiasts on the Si variant. This article explains the breakdown by model and what buyers would find in dealerships.
Transmission options by trim
Overview of which transmissions were available on the 2015 Civic by major trim level:
- Civic Si: 6-speed manual transmission only (manual-only, performance-oriented).
- Other trims (LX, EX, EX-L): Continuously variable transmission (CVT) automatic for fuel efficiency and smooth operation.
In practice, this means that if you’re shopping for a 2015 Civic and want an automatic, you’re most likely looking at a CVT-equipped model unless you’re after the Si’s sport-focused manual gearbox. If you want a manual in this year, the Si is the model that offers it.
Summary
The 2015 Honda Civic offered two primary transmissions: a CVT automatic for most trims and a six-speed manual on the Civic Si. Always verify the specific car’s build sheet to confirm the exact transmission configuration.
