How much trans fluid is needed for a filter change in 07 Chevy Impala?

You won't need to drain the entire transmission to change the filter on a 2007 Chevy Impala. However, you'll lose some fluid during the process. The amount lost will vary depending on how much remains in the torque converter and transmission pan.

Expect to need between 3 and 5 quarts of transmission fluid to replenish what's lost after the filter change. It's best to have a bit extra on hand just in case. Always check your owner's manual for the specific type of transmission fluid recommended for your Impala's transmission (likely Dexron VI).

Important Note: A simple filter change isn't a complete transmission fluid change. A thorough flush and fill requires considerably more fluid. If your transmission fluid is old or dirty, consider a complete fluid exchange instead of just a filter change. This is usually done by a professional.
