The automatic transmission fluid capacity for a 2002 Chevrolet Avalanche depends on whether it has a 4L60E or 4L65E transmission. There's no single answer. You
must check your owner's manual. The manual will specify the exact capacity for your vehicle's transmission.
Trying to determine it without knowing the specific transmission is unreliable and could lead to underfilling or overfilling, which can damage the transmission.
