Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and securely raised with jack stands.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Check Transmission Fluid

Remove the transmission dipstick and check for proper fluid level.
If low, top off with the manufacturer-recommended ATF (Toyota Genuine ATF WS).
Inspect fluid for burnt smell or metal shavings; replace if necessary.

3. Inspect Shift Linkage

Locate the shift linkage connected to the transmission.
Inspect for any looseness or damage; tighten or replace as needed.
Ensure the linkage is properly aligned and engages without obstruction.

4. Test Brake Switch

Locate the brake switch near the brake pedal.
Use a multimeter to test if the switch is functioning (should show continuity when pedal is pressed).
Replace the brake switch if it fails the test.

5. Check for Transmission Faults

If the above steps do not resolve the issue, consider removing the transmission pan to inspect the filter.
Replace the filter and fluid if they are dirty or clogged.
Reinstall the pan with new gasket and torque bolts to manufacturer specifications (typically around 12-14 lb-ft).

6. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the vehicle and test shifting into reverse; observe for any abnormal noises or behavior.
