How many quarts of transmission fluid does a Chevy HHR take?
The typical answer is that most Chevy HHRs with the factory automatic transmission take about 9 quarts for a full fill (including the torque converter), while manual transmissions usually require about 2 to 3 quarts. Exact capacity depends on the specific transmission model and whether you’re draining only the pan or performing a full system service.
Two common transmission setups in the HHR
Transmission capacity varies by setup. The automatic and manual configurations used in the HHR have different total volumes, and the amount you need changes with whether you’re doing a pan drain/refill or a complete fluid exchange.
Automatic transmission (4T45-E) capacity
These figures reflect the typical capacities of the common automatic setup used in most Chevy HHRs.
- Full system capacity (including the torque converter): about 9 quarts.
- Pan drain and refill capacity (fluid added through the pan only, no torque converter drain): about 4–5 quarts.
Note that exact values can vary by year, engine, and service procedure. Consult the owner’s manual or GM service documentation for your VIN for precise figures.
Manual transmission capacity
For HHRs equipped with a manual transmission, the capacity is lower.
- Typical total capacity: about 2–3 quarts.
As always, confirm the exact specification for your vehicle’s exact transmission model and year in the service manual or with a GM dealer.
How to confirm the exact capacity for your vehicle
To ensure you use the correct amount and type of transmission fluid, follow these steps:
- Identify the transmission model code stamped on the transmission case or in the vehicle’s service documentation; most HHRs use the 4T45-E automatic or a GM 5-speed manual.
- Consult the owner’s manual or GM service bulletin for your year and engine/transmission combination to confirm capacity and specs (Dexron VI for most automatics).
- If performing a drain and fill, plan for roughly 4–5 quarts for a pan-only change, and up to about 9 quarts for a full fluid exchange that includes the torque converter.
Note: If you’re unsure, perform a measured fill and check the level according to GM procedure to avoid overfill or underfill.
Summary
In practical terms, an automatic-transmission HHR typically needs about 9 quarts for a complete fill (including the torque converter), while a manual-transmission HHR uses roughly 2–3 quarts. Always verify with your specific VIN, year, and transmission code to account for variations in model and service scope.

How many quarts of transmission fluid do I need 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.
