The 2001 Chevy Tahoe requires
between 3.5 and 4 quarts of transmission fluid for a complete fill. However, this is just an approximation. The exact amount needed will depend on whether you're performing a drain and fill (which only replaces a portion of the fluid) or a complete flush and fill (which aims to replace all the fluid). A complete flush will use the higher amount.
It's crucial to consult your owner's manual. This will give you the most accurate information specific to your vehicle's transmission type (e.g., 4L60E, 4L65E, etc.). The manual might also specify the type of transmission fluid recommended. Using the wrong fluid can damage your transmission.
