Typically, the 2009 Pontiac G6 uses a four-speed automatic transmission; a five-speed manual was available for the 2.4-liter Ecotec version, and some 2.4L cars could also be equipped with a four-speed automatic.
Engine and transmission options
The following summarizes the common factory transmissions paired with the two engines offered in the 2009 G6. The exact setup can depend on trim and production date, so verify on your specific vehicle if needed.
- 3.5L V6 engine: Four-speed automatic transmission.
- 2.4L Ecotec inline-four engine: Five-speed manual transmission is available on several trims; a four-speed automatic transmission is also offered as an alternative.
Given the variations across model years and markets, some cars may differ in transmission type. Checking your car’s labeling, owner’s manual, or window sticker can confirm the exact pairing for your vehicle.
How to verify the transmission in your G6
If you want to confirm your specific car’s transmission, use these methods. They help identify which transmission is installed without relying on memory from brochure features.
- Inspect the gear selector: If you see a PRNDL layout, it’s an automatic. If there are gears labeled 1–5 (and a separate R for reverse), it’s a manual.
- Check for a clutch pedal: A visible clutch pedal on the far left indicates a manual transmission.
- Look for build documentation: The window sticker, owner’s manual, or a service invoice often lists the transmission type.
- VIN-based confirmation: The Vehicle Identification Number (VIN) and GM service databases can specify the exact transmission installed at factory or in service records.
In summary, the 2009 Pontiac G6 offered two main powertrain paths with different transmissions: the V6 model paired with a four-speed automatic, and the 2.4L Ecotec model available with either a five-speed manual or a four-speed automatic depending on the exact configuration.
Summary
The 2009 Pontiac G6’s transmission depends on the engine: the 3.5L V6 uses a four-speed automatic, while the 2.4L Ecotec can be paired with either a five-speed manual or a four-speed automatic. To be certain, check the gear selector, clutch presence, official documents, or the VIN for an exact match.
