The exact location varies slightly depending on the transmission type (automatic or manual) in your specific Malibu. However, it's generally found on the transmission case itself, near the top or side. It's usually a relatively small sensor with a single wire connector.
To locate it precisely:
1. Consult your repair manual: A factory service manual for your specific year and model Malibu will give the precise location and diagrams. This is the most reliable method.
2. Use a repair database: Online repair databases (like AllDataDIY or Mitchell 1) often have diagrams and location information.
3. Search online forums: Search for forums related to 2000 Chevy Malibu repairs. Someone might have posted pictures or descriptions of the sensor's location.
Remember to disconnect the negative battery terminal before working near any sensors or electrical components.
