Solution

1. Preparation

Gather necessary tools and safety equipment.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to avoid electrical shorts.

2. Check Transmission Fluid

Tools Required: Transmission dipstick, funnel
Remove the transmission dipstick, wipe it clean, and reinsert it fully.
Pull out the dipstick again to check the fluid level. If low, add the appropriate type of ATF (Toyota WS) through the dipstick tube.
Inspect the fluid's color and smell; it should be bright red and have no burnt odor.

3. Inspect Shift Linkage

Tools Required: Socket set, wrench
Locate the shift linkage under the vehicle.
Visually inspect for any damage, loose connections, or misalignment.
Adjust the linkage if necessary to ensure proper engagement.

4. Replace Brake Light Switch

Tools Required: Screwdriver, socket set
Locate the brake light switch near the brake pedal.
Disconnect the electrical connector from the switch.
Remove the switch using a socket or screwdriver.
Install the new brake light switch and reconnect the electrical connector.

5. Address Transmission Control Module (TCM) Issues

Tools Required: OBD-II scanner
Connect the OBD-II scanner to the vehicle's diagnostic port.
Check for any error codes related to the TCM.
If codes are present, follow manufacturer specifications for additional diagnostics or TCM replacement.
