* Automatic Transmission: Expect to need between 3 and 4 quarts for a complete fluid change. Always check your owner's manual for the precise amount recommended by Chevrolet for your specific Cavalier's transmission.
* Manual Transmission: Manual transmissions don't require regular fluid changes in the same way automatics do. Fluid changes are generally only needed if there's a problem, and the amount is much smaller, typically less than a quart.
Crucially: You should consult your owner's manual for the exact capacity specified for your vehicle's transmission type. This is the most reliable source of information.
