The 2010 Nissan Altima 2.5 S uses Nissan’s Xtronic Continuously Variable Transmission (CVT). It’s not a traditional automatic or a manual gearbox.
In this article, we explain what that means for the car’s performance, how it differs from the V6-equipped models in the same year, and what owners should know about CVT maintenance and reliability for the 2010 Altima.
Transmission options in the 2010 Altima lineup
To put the 2.5 S into context alongside other trims, here are how transmissions were allocated across the 2010 Altima lineup.
- 2.5 S (4-cylinder): Xtronic CVT with manual shift mode and drive modes typical of CVTs.
- 3.5 SE/3.5 SL (V6): 5-speed automatic with manual mode (not CVT).
The Altima's four-cylinder transmission is CVT designed for efficient, quiet operation, while the V6 trims use a traditional automatic. This distinction helps explain differences in driving feel and maintenance needs across the lineup.
What the CVT means for driving and maintenance
The CVT provides smooth acceleration and often better fuel economy on the 2.5 S, but it can feel different from a conventional automatic because it doesn’t shift through gears. Most CVTs in this era offer a manual shift mode for a more engaged feel, usually via a +/- on the shifter or steering wheel.
- Maintenance: Use Nissan NS-2 CVT fluid and check levels regularly; have the CVT fluid replaced per the factory-recommended schedule (often around 60,000 miles, though refer to the owner's manual or dealer guidance).
- Potential issues: CVTs can develop issues like whining, slipping, or surging if fluid is old or leaking; address problems promptly with a Nissan dealer.
Proper maintenance is crucial for longevity of the CVT in the Altima 2.5 S. Always use fluids specified by Nissan for CVT and consult a dealer for service intervals.
Driving impressions
Expect smooth acceleration with continuous gearing and a quiet ride in most conditions. The CVT can feel less immediate than a traditional automatic when flooring the accelerator, but the engine remains in its efficient range. The manual mode helps when you want more control, such as merging or climbing hills.
Summary: The 2010 Nissan Altima 2.5 S is equipped with a Continuously Variable Transmission (CVT) called Xtronic, paired with the 2.5L four-cylinder engine. The V6 trims use a traditional 5-speed automatic. For maintenance, use NS-2 CVT fluid and follow the Nissan-recommended intervals to keep the transmission performing well. Always verify your specific VIN’s factory specs, as options can vary by market and production batch.
