Transmission Shift Lever Assembly

What is an Automatic Transmission Shift Lever Assembly?

The automatic transmission shift lever assembly is a component of a vehicle's transmission system that allows the driver to select different gears, such as Park, Neutral, Drive, or Reverse. Shift levers are typically mounted to the steering column, console, or floor of a vehicle, and are connected by a system of linkages or cables to the transmission shift arm. When the driver moves the shift lever, it activates the shift linkage, and transmits the intended position to the transmission to select the appropriate gear or driving mode. Shift levers often also have gates that prevent the vehicle from slipping out of gear and to make finding the correct gear easier. Shift levers may suffer damage or break with use and over time, which can make it more difficult or impossible to get the vehicle into gear. When the shift lever is no longer engaging or working as it should, it can also indicate an issue with the lever or linkage assembly. In some cases, these linkages can be readjusted to restore operation, but a complete diagnosis may be necessary to determine the source of the issue.
