However, there's a crucial caveat: The exact location *within* the transmission varies slightly depending on the specific transmission type (automatic or manual) your Cavalier has. You'll need to consult a repair manual specific to your car's transmission type to pinpoint its precise location.
Without knowing your transmission type, any more specific guidance risks being inaccurate. A repair manual (physical or online) or a detailed diagram of your specific transmission is your best bet for accurate placement.
