Shift Linkage: Description and Operation






DESCRIPTION
The range select mechanism consists of a selector lever (on the floor/center console in the driver's compartment), push-pull cable, linkages, manual valve, parking pawl, etc.

OPERATION
When the selector lever is moved either forward or backward, the push-pull cable moves in the corresponding direction. This turns the manual shaft by way of the range selector lever. At this point, the pin at the end of the range selector lever turns the [1][2]inhibitor switch arm to transmit a range signal to the control unit.

A manual plate and manual lever are attached to the manual shaft. The manual plate is fan-shaped and is provided with seven grooves on its edge corresponding to shift ranges (from "P" to "1"). A detent spring roller fits into the groove corresponding to the range selected. This regulates effort required to operate the selector lever.

A hydraulically controlled manual valve is installed on the lower pin of the manual lever. It slides in response to rotation of the manual shaft, thereby selecting an oil passage inside the lower valve body in response to the position (P. R. N. D, 3, 2 or 1) of the selector lever.

A parking rod located on the upper portion of the lever mechanically holds the output shaft when the selector lever is shifted to "P".

A shift lock mechanism is incorporated in the selector lever mount.
