The Chrysler 300 gearbox sits at the heart of a quintessentially American large saloon — over five metres long and renowned for its style and performance. Robust as it is, the transmission still demands careful maintenance. At EDEN BOITES, specialists in exchange gearboxes, we bring you our complete maintenance and repair guide for the Chrysler 300 gearbox.
How the Chrysler 300 gearbox evolved over the generations
Since its launch in 2004, the Chrysler 300 has carried on the tradition of the luxury saloon with a front-mounted V8 and rear-wheel drive. It was offered with two V6 engines and a V8 HEMI, paired with a 4- or 5-speed automatic gearbox depending on the variant.
In 2011, following the merger with the FCA group, the 300 was sold in Europe under the Lancia Thema badge, with a Pentastar petrol V6 and a diesel V6. European sales ended in 2014. Since then, the 300 has been reserved for the American market, with V6 and V8 HEMI engines and a ZF automatic gearbox ranging from 5 to 8 speeds.
What sets the Chrysler 300 gearbox apart
Every gearbox fitted to the 300 incorporates a torque converter, making it more costly to manufacture and maintain than a manual gearbox. This component relies on three main elements:
- an input turbine, connected to the engine;
- an output turbine, connected to the gearbox;
- a stator, connected to the casing.
When the driver accelerates, the input turbine forces fluid onto the output turbine, transferring energy to the driveshaft. The torque converter is one of the most heavily stressed components in the gearbox: repairing it requires genuine expertise and the correct transmission fluid.
Essential maintenance steps
Looking after your 300 properly is the key to its longevity. To keep the gearbox in good shape:
- check the gearbox oil level regularly, with the engine cold and switched off;
- follow the manufacturer's service intervals and replace the gearbox filter at every service;
- use a transmission fluid that meets your model's specifications;
- have the gearbox inspected at least once a year and report any noise, vibration or difficulty selecting gears;
- drive smoothly and avoid overloading the vehicle.
Even with these precautions, a fault can still occur. A simple fluid change will sometimes resolve a minor issue, but in the event of serious damage, a complete exchange is often the only solution. Browse our exchange gearboxes for the Chrysler 300.
Frequently asked questions
Which gearbox does the Chrysler 300 use?
A 4- or 5-speed automatic on early generations, then a ZF automatic with 5 to 8 speeds on later versions.
Why is the torque converter so sensitive?
It is one of the most heavily stressed components in the gearbox. When it fails, the repair requires real expertise and the correct transmission fluid.
