Two transmissions were used in the 2007 Altima: a Nissan Xtronic continuously variable transmission (CVT) paired with the 2.5-liter four-cylinder engine, and a traditional five-speed automatic paired with the 3.5-liter V6 engine.
In the 2007 Altima lineup, engine choice determined the transmission type. The four-cylinder model paired with a CVT, while the V6 used a conventional automatic that shifts through five fixed gears. The CVT is designed for smooth acceleration and improved fuel efficiency, whereas the V6’s five-speed automatic provides more traditional gearing and driving feel. Buyers should verify the exact configuration for any given car, as trims and market specifics can vary slightly.
Transmission options by engine
These are the two powertrains and their corresponding transmissions you’ll find in the 2007 Altima.
Two powertrains, two transmissions
- 2.5-liter four-cylinder (QR25DE): Xtronic CVT (continuously variable transmission).
- 3.5-liter V6 (VQ35DE): 5-speed automatic transmission.
Practically speaking, this means the driving experience can feel quite different depending on the chosen engine. The CVT aims for ultra-smooth, seamless acceleration and often better real-world fuel economy, while the V6 with a conventional automatic offers distinct gear changes and a different towing/acceleration character.
Maintenance and reliability notes
Maintenance considerations are important, especially for CVT-equipped models. Nissan recommends using the proper CVT fluid and adhering to the suggested service intervals, which typically include fluid checks and changes to maintain performance and longevity. The V6’s five-speed automatic, while traditional, also benefits from regular fluid changes and inspections for wear, leaks, and shifting consistency.
To help owners and shoppers, here are practical guidelines:
- Always verify the exact transmission on the vehicle via the VIN or the window sticker; trims and regional specifications can differ.
- Use the correct fluid: CVT fluid for the 2.5L CVT-equipped models; avoid standard automatic transmission fluid in CVT units.
- Monitor for signs of trouble: unusual noises, slipping, shuddering, delayed engagement, or harsh shifts warrant prompt inspection.
Proper maintenance and correct fluid use are key to prolonging the life of either transmission in the 2007 Altima.
What to check when buying a used 2007 Altima
When evaluating a used 2007 Altima, confirm the transmission type and test-drive both configurations if possible. CVT-equipped versions should accelerate smoothly without noticeable hesitations or jerking, while V6 models should shift cleanly through gears without slipping or lag.
Summary
The 2007 Nissan Altima offered two transmissions based on engine choice: a Nissan Xtronic CVT with the 2.5-liter four-cylinder and a traditional five-speed automatic with the 3.5-liter V6. This distinction affects driving feel, maintenance requirements, and what to look for when buying a used model. Verifying the exact configuration and maintenance history is essential for an informed purchase.
