The 2008 Altima uses two automatic transmissions depending on the engine: a 4-speed automatic with the 2.5-liter four-cylinder, and a 5-speed automatic with the 3.5-liter V6. There is no manual transmission option in the 2008 lineup.
In more detail, buyers choosing the base 2.5-liter Altima will experience a four-speed automatic, while the V6-powered models are paired with a five-speed automatic. Both configurations employ a conventional automatic gearset, with some trims offering a manual shift mode to closely mimic manual control.
Transmission options by engine
The following summarizes the two configurations offered on 2008 Altima models.
- 2.5-liter four-cylinder engine: 4-speed automatic transmission (4AT), with optional manual shift mode on supported trims.
- 3.5-liter V6 engine: 5-speed automatic transmission (5AT), with optional manual shift mode on supported trims.
In practice, the 2008 Altima offered two automatic transmissions rather than a manual option, with the choice driven by engine size.
What to check when buying a used 2008 Altima
When evaluating a used 2008 Altima, consider the condition and responsiveness of the automatic transmission, as well as the vehicle’s maintenance history. A well-maintained unit should shift smoothly across gears without slippage or hard engagement.
- Check for smooth shifting between gears in all driving modes to detect slipping or delayed engagement.
- Inspect the transmission fluid: it should be clean and red; dark or burnt-smelling fluid can indicate issues.
- Review maintenance records for any transmission service, fluid changes, or recalls related to the transmission.
With proper care and service history, a 2008 Altima with either the 4-speed or 5-speed automatic can offer reliable performance.
Summary
The 2008 Nissan Altima paired the 2.5-liter four-cylinder with a 4-speed automatic and the 3.5-liter V6 with a 5-speed automatic. There was no manual transmission option for that model year, and both transmissions offered a manual shift mode on some trims. Buyers should verify transmission condition and service history when assessing a used example.
