The Chrysler 300 is a full-size sedan known for its comfort, bold styling, and smooth performance. To keep it running strong, maintaining the transmission is essential. One of the most important aspects of transmission maintenance is knowing the correct fluid type and capacity. Using the wrong fluid or the wrong amount can cause slipping, overheating, and long-term transmission damage. This guide covers the Chrysler 300 transmission fluid capacity by model year and transmission type, along with fluid recommendations and service tips.
Quick Answer – Chrysler 300 Transmission Fluid Capacity
- 2005–2010 Chrysler 300 (4-speed 42RLE automatic): ~4 quarts (drain & fill), ~8.8–10 quarts (full fill) – ATF+4
- 2005–2010 Chrysler 300 (5-speed NAG1 / 722.6 automatic): ~5.5 quarts (drain & fill), ~9.7 quarts (full fill) – ATF+4 or MB 236.14 equivalent
- 2011–2014 Chrysler 300 (5-speed NAG1 automatic): ~5.5 quarts (drain & fill), ~9.7 quarts (full fill) – ATF+4
- 2012–Present Chrysler 300 (8-speed ZF 8HP automatic): ~4.5–5 quarts (drain & fill), ~8.5–9 quarts (full fill) – Mopar 8&9 Speed ATF / ZF Lifeguard 8
Recommended Transmission Fluids
- Mopar ATF+4 Automatic Transmission Fluid – Required for Chrysler 300 models with 4-speed and 5-speed automatics.
- Mopar 8&9 Speed ATF – Designed for Chrysler 300 models with the ZF 8-speed transmission.
- Ravenol ATF 8HP Fluid – High-quality alternative to OEM for ZF 8-speed transmissions.
Why Transmission Fluid Matters
Transmission fluid serves three main purposes: lubrication, cooling, and hydraulic operation. Using the correct fluid ensures:
- Smoother shifting under normal and heavy loads
- Lower operating temperatures to prevent overheating
- Extended transmission life by reducing wear
Filling with the wrong fluid can cause damage, which is why Chrysler specifies ATF+4 for older models and Mopar 8&9 Speed ATF for newer 8-speed transmissions.
DIY Transmission Fluid Change – Step by Step
Changing transmission fluid at home is possible with the right tools:
- Warm up the transmission with a short drive.
- Safely lift and support the car.
- Remove the drain plug or transmission pan (depending on model).
- Allow fluid to drain completely.
- Replace the filter (common on 4-speed and 5-speed models).
- Reinstall the pan with a new gasket.
- Refill with the correct fluid through the dipstick (older) or fill plug (newer 8-speed).
- Start the engine, cycle through all gears, and check fluid level.

FAQ Section
How often should I change transmission fluid in a Chrysler 300?
Most experts recommend changing transmission fluid every 60,000–100,000 miles. If you tow or drive aggressively, shorter intervals are better.
Does the Chrysler 300 have a transmission dipstick?
Older models (4-speed and 5-speed) have a dipstick. The newer 8-speed ZF transmission is sealed and requires a special procedure to check fluid level.
Can I use Dexron VI in my Chrysler 300?
No. Chrysler specifically requires ATF+4 for 4- and 5-speed models, and Mopar 8&9 Speed ATF for 8-speed models. Using Dexron VI can cause shifting issues.
How much fluid is replaced in a drain & fill?
Typically 4–5 quarts depending on the transmission. A full capacity change requires 8–10 quarts.
What happens if I overfill transmission fluid?
Overfilling can cause foaming, slipping, and overheating. Always fill to the correct level only.
Conclusion
The Chrysler 300 transmission fluid capacity depends on the year and transmission type. The 4-speed and 5-speed models require ATF+4, while the 8-speed ZF transmission requires Mopar 8&9 Speed ATF. Capacity ranges from 8.5 to 10 quarts for a full fill, with drain & fill services replacing about 4–5 quarts. Using the right fluid and maintaining proper levels is the best way to ensure smooth performance and long transmission life.
