[edit] Vehicles with Autostick

The Dodge Intrepid ES and Eagle Vision TSi were the first automobile models in North America that came equipped with the Autostick system as an option, later standard equipment on the 99 Chrysler 300M. it was added to the JA cars on the 98 Stratus. Many Chrysler models today come with this system, including the 300, 300C, Charger, Sebring, and Crossfire. In the 1970s Volkswagen sold a model of 'Autostick' Superbeetle.

[edit] System advantages

Ability to manually select gears
Ability to start from 2nd or 3rd in inclement weather to improve traction
Allows downshifting while coming down steep inclines to maintain speed.
Improved performance with quicker, more firm shifts

[edit] System components and operation

Components of the Autostick system in the first Chrysler vehicles to have the design included a different TCM (Transmission Control Module), shift assembly, and gauge cluster. The gauge cluster includes a read-out to let the driver know which gear is selected.

The system works by dropping the shifter down into a gated area on the shift assembly which allows the shifter to be pushed to the right (up-shift) or to the left (down-shift). When the driver pushes the shifter in either of these directions the assembly sends a signal to the TCM to shift up, or down depending on the driver's actions. Dropping the shifter into the Autostick gate while the vehicle is moving will simply keep the vehicle in the current gear selected.

[edit] System failsafes

If the user does not shift while driving in the Autostick mode, the transmission will automatically up-shift at redline to prevent engine/transmission damage, and will not downshift into redline. When coming to a complete stop, the system will automaticly return to first gear. According to the owner's manual in the event of a critical falure the system will revert to a full automatic mode.
