The amount of transmission fluid required for a 2000 Chevy Silverado 1500 extended cab depends on the type of transmission it has. There's no single answer. To be certain, you
must consult your owner's manual. The manual will specify the capacity for your specific truck's transmission (likely either a 4L60E or 4L65E automatic, or a manual transmission).
Trying to determine the capacity without knowing the transmission type could lead to underfilling or overfilling, both of which can damage your transmission.
