New eight-speed transmission introduced by Chrysler

Will increase fuel economy


At the rear of the shifter is a gate that allows for down- and up-shifting by the driver.

Once the vehicle is in the Sport mode, the driver can use either the console-mounted shifter or a pair of paddle controls located on the steering wheel.

Once the Sport mode is selected, shift times are quicker and engine rpm is allowed to increase for a more performance- oriented acceleration and higher shift dynamics.

Acceleration times for the Dodge Charger and Chrysler 300 for 0-to-60 mph are 7.2 seconds.

Internally, the 845RE transmission features four gear sets and five shift elements (multi-disc clutches and brakes) inside the transmission. With fewer open shift elements, drag losses due to multiple parts rotating relative to one another, are reduced.

Additionally, lower viscosity transmission fluid is used resulting in improved transmission efficiency and fuel economy improvements especially during cold environments or vehicle start-up. The 845RE also is "fill for life" not requiring oil changes during normal driving conditions.

The all-new automatic transmission will initially be purchased through ZF. Production by Chrysler at its Kokomo transmission facility under license by the German-based company is slated following introduction.
