Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent any electrical issues during the repair.

2. Check and Refill Transmission Fluid

Locate the transmission dipstick and remove it.
Wipe it clean and reinsert it to check the fluid level.
If low, add the appropriate type of transmission fluid (Toyota WS fluid) through the dipstick tube.
Start the engine and cycle through all gears, allowing the fluid to circulate.
Recheck fluid level and add as necessary.

3. Inspect Transmission Linkage

Locate the transmission linkage near the transmission housing.
Visually inspect for any signs of wear or damage.
Adjust the linkage if misaligned or replace it if damaged.

4. Replace Transmission Range Sensor

Disconnect the battery again.
Locate the transmission range sensor (usually near the transmission).
Unplug the electrical connector and remove the mounting bolts.
Install the new range sensor and secure it with bolts.
Reconnect the electrical connector.

5. Reassemble and Test

Reconnect the battery.
Start the vehicle and check for any warning lights.
Test the transmission by shifting into reverse to ensure proper engagement.
