The 2012 Altima offers two transmissions depending on the engine: a continuously variable transmission (CVT) for the 2.5-liter four-cylinder versions, and a traditional 5-speed automatic for the 3.5-liter V6 model.
Transmission options by engine
There are two primary configurations for the 2012 Altima that align with its engine options. Here is how the lineup pairs transmissions with engines.
- 2.5-liter four-cylinder models (S, SV, SL) are paired with Nissan's Xtronic CVT. This setup emphasizes fuel economy and smooth acceleration, with a manual shift mode available on many trims.
- 3.5-liter V6 models are paired with a conventional 5-speed automatic transmission, delivering traditional stepped gear shifts and strong performance with the V6 engine.
Most of the 2012 Altimas you see with better fuel economy will have the CVT, while the V6 models will have the 5-speed automatic. To be certain about a specific car, check the window sticker or VIN.
How to verify your Altima’s exact transmission
To confirm the transmission on a particular 2012 Altima, consult the owner’s manual, the window sticker, or the vehicle’s VIN. The VIN can be decoded to reveal the original transmission type, or a Nissan dealership can confirm it from the build data.
Quick checks you can perform
Look at the gear selector and the transmission badge: CVTs are typically paired with a drive selector that does not show fixed gears in the same way as a traditional automatic, whereas the V6 with a 5-speed automatic will display a standard PRNDL arrangement with clear fixed steps. Keep in mind that trim variations can affect the exact display.
Summary: The 2012 Nissan Altima uses a CVT with the 2.5L engine and a 5-speed automatic with the 3.5L V6. Verify on a specific vehicle via VIN or window sticker.
