The transmission shifter position is communicated to the PCM by the Transmission Range Sensor. This information is used by the PCM to determine which gears of the transmission to activate or deactivate. Failure of the TR sensor can result in a falling-out-of-gear condition, incorrect gear starts, and no upshifts.
Is the transmission range sensor the same as the neutral safety switch?
Transmission Range Sensor and Neutral Safety Switch prevent the starter from operating in any gear but Park and Neutral. In the starter control circuit, the sensors tell the TCM what gear it is currently in.
What happens when a transmission sensor goes bad?
Forceful or Inappropriate TransitionsThe PCM will not be able to correctly control the shifting of gears in the transmission unless it receives a valid speed signal from these sensors. Transmissions may shift more quickly or with greater jerkiness as a result of this.
What does transmission range switch do?
In order for your car’s powertrain module to know what gear you’re in, you need a transmission range switch (also known as the neutral safety switch). Only when the transmission range switch is in Park or Neutral can your car start.
What is another name for a transmission range sensor?
The neutral safety switch, or PRNDL input, is another name for the transmission range sensor. Shift lever position and gear selection are communicated to the TCM or PCM via this device.
How much does it cost to replace a transmission range sensor?
How much does it cost to replace the transmission range sensor? The average cost of a transmission range sensor replacement is $350. The typical price range is $200 to $500, with the lower end being the most affordable.
How do you adjust a transmission range sensor?
It is necessary to loosen a nut that secures a transmission control lever to a transducer. Remove the TR sensor by removing the two bolts holding it in place. Use the Transmission Range Sensor Alignment Tool T97L-70010-AH or an equivalent to align the TR sensor slots. Maintain 7–9 ft of torque on the TR sensor retaining bolts.
