Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, screwdrivers, transmission fluid dipstick.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the battery to prevent electrical shorts during repairs.

2. Check Transmission Fluid

Remove the transmission dipstick and wipe it clean.
Reinsert the dipstick, then remove it again to check the fluid level.
If the fluid is low, top it off with the correct specification transmission fluid (e.g., Toyota ATF WS).
If the fluid is discolored or has a burnt smell, a transmission fluid change may be necessary.

3. Inspect Gear Shift Linkage

Remove any panels or covers that obstruct access to the gear shift linkage.
Visually inspect the linkage for wear, damage, or disconnection.
If damaged, replace the gear shift linkage components.

4. Test the Clutch Pedal (Manual Transmissions)

Ensure the clutch pedal has the correct free play (typically around 1-2 inches).
If the clutch feels spongy or does not return, check for hydraulic leaks or air in the hydraulic line.
If necessary, bleed the clutch system or replace the clutch master/slave cylinder.

5. Check Starter Interlock System

Inspect the wiring and connections to the starter interlock switch.
Ensure the switch functions properly; if not, replace it.
Test the system by attempting to shift out of park while pressing the brake pedal.

6. Reconnect Battery and Test

Reconnect the battery terminals securely.
Start the vehicle and attempt to shift through the gears while stationary to ensure proper engagement.
