Keeping your 2014 Chrysler 300S running smoothly for years to come involves paying attention to the fluids that keep its complex systems operating in harmony. Among the most critical is the transmission fluid, which acts as both a lubricant and a hydraulic fluid for your car’s gearbox. Whether you’re a seasoned DIY enthusiast or simply want to be more informed for your next service appointment, knowing the correct transmission fluid capacity and type is essential. This knowledge helps prevent costly damage and ensures your powerful sedan continues to deliver that signature, smooth driving experience.
This guide is specifically designed to provide you with the accurate information you need for your 2014 Chrysler 300S. The exact transmission fluid capacity isn’t a one-size-fits-all number; it depends heavily on which transmission and engine combination your vehicle has. Our 2014 Chrysler 300S Transmission Fluid Capacity Guide will walk you through the different possibilities, from the potent V6 to the mighty HEMI V8, and explain everything you need to know about this vital maintenance task.
Why the Right Transmission Fluid Matters for Your 300S
Think of your transmission fluid as the lifeblood of your gearbox. In an automatic transmission like the ones in the 2014 Chrysler 300S, it does a lot more than just prevent metal parts from grinding against each other. It creates the hydraulic pressure needed to shift gears, helps cool the transmission, and keeps the seals conditioned. Using the incorrect fluid type, or not having enough fluid, can lead to a cascade of problems. You might experience harsh or delayed shifting, slipping gears, overheating, and ultimately, a transmission failure that requires a very expensive repair or replacement. Sticking to the manufacturer’s specifications is the best way to protect your investment.
Identifying Your 2014 Chrysler 300S Transmission
Before you can determine the correct fluid capacity, you need to know which transmission is in your car. The 2014 Chrysler 300S primarily came with two different automatic transmissions, and the choice is directly tied to the engine.
If your 300S is equipped with the 3.6L Pentastar V6 engine, it uses the ZF 8HP70 8-speed automatic transmission. This is a sophisticated and widely praised transmission known for its quick, smooth shifts and excellent efficiency.
If your 300S boasts the powerful 5.7L HEMI V8 engine, it is paired with the Mercedes-Benz-derived W5A580 5-speed automatic transmission. This robust gearbox is designed to handle the high torque output of the HEMI engine.
The easiest way to confirm your transmission type is to check your owner’s manual or look up your vehicle’s specifications using your VIN (Vehicle Identification Number).
Your 2014 Chrysler 300S Transmission Fluid Capacity Guide
Now for the specific numbers. The transmission fluid capacity varies significantly between the two transmissions, and it’s also different for a simple fluid drain-and-fill versus a complete transmission flush. A drain-and-fill is the most common DIY method and typically replaces about 40-50% of the total fluid, as a significant amount remains in the torque converter and transmission cooler lines.
For the 3.6L V6 with the 8-Speed Transmission:
- Total Fill Capacity: Approximately 9.5 quarts (9.0 liters)
- Drain and Refill Capacity: Approximately 4-5 quarts (3.8-4.7 liters) after a pan drop and filter change.
- Fluid Type: This transmission requires a specific fluid. The original factory fill is Mopar ATF+4, but for services, Mopar 8&9-Speed ATF is the specified fluid. It is crucial to use the correct fluid designed for this 8-speed transmission.
For the 5.7L V8 with the 5-Speed Transmission:
- Total Fill Capacity: Approximately 13.2 quarts (12.5 liters)
- Drain and Refill Capacity: Approximately 5-6 quarts (4.7-5.7 liters) after a pan drop and filter change.
- Fluid Type: This transmission uses Mopar ATF+4 fluid. It is important not to use other generic “multi-vehicle” fluids unless they explicitly meet the ATF+4 specification.
A Step-by-Step Look at the Fluid Change Process
Changing the transmission fluid in a 2014 Chrysler 300S is a manageable project if you have some mechanical experience. The process generally involves safely raising and supporting the vehicle, removing the transmission pan to drain the old fluid, replacing the transmission filter and pan gasket, and then refilling with new fluid through the dipstick tube. A critical final step is checking the fluid level with the transmission at operating temperature and the engine running, as per the manufacturer’s procedure. An incorrect fluid level can be just as harmful as using the wrong fluid. If you are not comfortable with any part of this process, consulting a professional technician is always the safest choice.
Choosing the Correct Transmission Fluid
Using the exact fluid specified by Chrysler is non-negotiable for the health of your transmission. The 8-speed and 5-speed transmissions have very different internal designs and require fluids with specific friction modifiers and viscosity ratings.
- For 8-Speed Models: Look for Mopar 8&9-Speed ATF (Part Number 68134349AA is a common example).
- For 5-Speed Models: Look for Mopar ATF+4 (Part Number 05142836AA is a common example).
Always purchase fluids from reputable sources to avoid counterfeit products that could damage your transmission.
When Should You Change the Transmission Fluid?
Chrysler often describes the fluid in these transmissions as “lifetime,” but this is under ideal conditions. For long-term reliability, most experts recommend a transmission fluid service more frequently. A good rule of thumb is to consider a drain-and-fill every 60,000 to 100,000 miles. If you do a lot of stop-and-go city driving, tow a trailer, or drive in extreme temperatures, you may want to perform this service on the lower end of that range, around 60,000 miles. Pay attention to how your car shifts; if you notice any hesitation or roughness, it might be time for new fluid.
Taking care of your 2014 Chrysler 300S’s transmission is one of the most important things you can do to ensure its longevity and performance. By using this guide to confirm your specific transmission fluid capacity and type, you can make an informed decision about maintenance. Whether you tackle the job yourself or provide the details to your trusted mechanic, using the right fluid in the right amount will help keep your 300S driving with the confidence and power it was built for.
