  1. Install the TRS (2) to the manual shaft. Make sure TRS locating pin rests in manual valve bore slot.
  2. Install the TRS/manual shaft retaining screw (1) (Figure 1) and torque to 5 Nm (45 in. lbs.) torque.
  3. Install the manual shaft seal (1)(Figure 2).
  4. Install valve body to the transmission.Valve Body - Installation

OPERATION The Transmission Range Sensor (TRS) communicates shift lever position (SLP) to the TCM as a combination of open and closed switches. Each shift lever position has an assigned combination of switch states (open/closed) that the TCM receives from four sense circuits. The TCM interprets this information and determines the appropriate transmission gear position and shift schedule. Since there are four switches, there are 16 possible combinations of open and closed switches (codes). Seven of these codes are related to gear position and three are recognized as "between gear" codes. This results in six codes which should never occur. These are called "invalid" codes. An invalid code will result in a DTC, and the TCM will then determine the shift lever position based on pressure switch data. This allows reasonably normal transmission operation with a TRS failure.

DESCRIPTION The Transmission Range Sensor (TRS) (2) (Figure 1) is mounted to the top of the valve body inside the transmission and can only be serviced by removing the valve body assembly. The electrical connector extends through the transmission case. The Transmission Range Sensor (TRS) has four switch contacts that monitor shift lever position and send the information to the PCM.
