Why shift lever wont move on 1995 Toyota Avalon?

The shift lever on a 1995 Toyota Avalon might not move due to several reasons, such as a faulty brake light switch, which prevents the shift interlock mechanism from disengaging. Additionally, low Transmission Fluid levels or a malfunctioning transmission can also cause this issue. Another possibility is that the ignition key is not in the "on" position or the vehicle is not properly in "Park." Lastly, a stuck or damaged shift cable may be the culprit.
