Toyota Camry Highlander Transmission Range Switch 84540-42010 Precise Shift Sensing

If your Camry or Highlander shows misalignment of gear indicator after gear engagement, or experiences noticeable gear shift hesitation or inability to start (especially Park cannot sense), the transmission gear position switch may be aging and failing. This part precisely senses the shift lever position and transmits signals to the ECU and dashboard to ensure correct gear recognition for starting and shifting operations. OEM number 84540-42010; fits Toyota Camry and Highlander. When installing, disconnect the negative battery terminal first, ensure the shift lever is in N, and torque bolts to factory spec to avoid signal misreadings caused by improper installation.
