How much transmission fluid does a 2009 Chevy Impala take?
For a typical 2009 Chevrolet Impala equipped with the common 4T65-E automatic transmission, plan on about 11 quarts (roughly 10.5 liters) of Dexron VI for a complete drain-and-fill including the torque converter. The exact amount can vary by ±1–2 quarts depending on service method and transmission condition.
The Impala's transmission capacity depends on whether you are performing a full service (pan drain, filter change, and torque converter drained) or a simpler pan-only drain-and-fill. Knowing the right amount helps ensure you don’t run low or overfill, both of which can affect shifting performance and longevity.
What kind of service are you performing?
Before listing the typical capacities, understand that there are two common service scenarios: a full transmission fluid service and a pan drain-and-fill. The quantities below reflect those scenarios and the amount of fluid you’ll generally need to add to reach the proper level.
- Full transmission service (drain pan, replace filter, and drain/refill torque converter): Typically about 11 quarts (approximately 10.5 liters) of Dexron VI. This reflects removing almost all old fluid and replacing it, including the converter’s holdback.
- Pan drain-and-fill only (no torque converter drain): Usually around 6–8 quarts of Dexron VI to bring the level back to the full mark after draining the pan, since some fluid remains in the torque converter and valve body. Check level with the dipstick after cooling and rechecking.
These figures are approximate and can vary based on transmission condition and factory specification. Always verify with the transmission dipstick after a warm-up cycle and recheck with engine running in Park/Neutral according to the service manual.
Why the numbers vary
Transmission fluid capacity is affected by the amount of fluid retained in the torque converter, oil cooler, and valve body passages. A new filter also changes the initial fill amount. Environmental temperature and driving habits may also influence how much you need to add to reach the correct level.
How to check and add fluid safely
Follow these steps to avoid overfilling or underfilling:
- Warm up the engine and transmission, then park on a level surface.
- With the engine running and the transmission in Park, check the fluid level on the dipstick and add gradually if low, rechecking until it reads at the proper range.
- Recheck after driving 10-15 minutes to ensure a stable level, due to changes as the fluid circulates.
Note: Use Dexron VI/VI-H Automatic Transmission Fluid as specified by GM for 4T65-E transmissions used in 2009 Impalas. Do not mix with other ATF types.
Summary: The typical total capacity for a 2009 Chevy Impala’s automatic transmission is about 11 quarts for a full service, with about 6–8 quarts for a pan-drain-and-fill. Always confirm with the dipstick and consult the owner's manual or a trusted technician for your specific vehicle's transmission and service plan.

How many quarts of transmission fluid for a drain and fill?
For a standard transmission fluid drain and fill, you'll typically need 3 to 5 quarts, but you should always measure the amount you drained and refill with the same amount to start, then check the level using the dipstick after running the engine. The exact amount varies by vehicle, and it's crucial to check the owner's manual or look up specifications for your specific make and model, as a drain and fill will not replace all the old fluid.
How to determine the right amount
- Drain the old fluid: Let the old fluid drain completely.
- Measure the drained fluid: Measure how much fluid was drained. This is your starting point for refilling.
- Refill with the measured amount: Put the same amount of new, correct transmission fluid back into the transmission. Using a funnel can help with this process.
- Start the engine: Start the vehicle and let it run for a few minutes, shifting through all the gears (Park, Reverse, Neutral, Drive) while holding the brake. This circulates the new fluid.
- Check the level: Turn the engine off and check the fluid level with the dipstick. Add more fluid in small increments if the level is low, or drain a small amount if it's too high.
- Re-check: Repeat the process of running the engine and checking the dipstick until the fluid level is correct according to the dipstick's hash marks for a "hot" reading.
Important considerations
- A drain and fill is different from a full transmission flush, which requires significantly more fluid (10-12 quarts or more) because it aims to replace all the fluid, including what's in the torque converter.
- You should always use the specific type of transmission fluid recommended by your vehicle's manufacturer to avoid damage.
- Some vehicles, like certain Land Rovers, do not have a dipstick and require a fluid extractor to add new fluid. Consult your owner's manual to be certain.
