Toyota Avalon 2012-2018 Transmission Range Switch 84540-33010 Replaces 84540-07010

Toyota Avalon (2012-2018) optional gear shift switch failure causes inaccurate instrument display, obvious shift flare, or inability to engage Park; this part transmits accurate gear signals to the transmission control unit to ensure smooth shifting, safe startup, and correct instrument display. OEM number 84540-33010 (alternatively 84540-07010) specifically for 2012-2018 Avalon. Install by disconnecting the battery negative and ensure the gear is in Park to avoid damaging internal contacts or causing signal mismatch.
