* 4-speed automatic transmission: This was the standard transmission for most trims.
* 6-speed automatic transmission: This was available as an option on some higher trims, particularly the LTZ.
To determine which transmission your specific 2007 Malibu has, you can:
* Check the vehicle's VIN: The Vehicle Identification Number (VIN) contains information about the car's specific features, including the transmission.
* Consult the owner's manual: The owner's manual will specify the transmission type for your particular vehicle.
* Look under the hood: The transmission type is often stamped on the transmission housing itself.
Please note that the availability of the 6-speed automatic transmission may vary depending on the specific trim level, engine option, and region where the vehicle was sold.
