Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the negative battery terminal to ensure safety during repairs.

2. Check and Replace Transmission Fluid

Locate the transmission dipstick (if equipped) or access the fluid fill plug.
Remove the dipstick or fill plug to check fluid level.
- If low, add manufacturer-recommended transmission fluid (Toyota ATF WS).
Inspect fluid condition. If it is dark or has a burnt smell, proceed to replace it.
Drain the old fluid using a drain pan. Remove the drain plug and allow fluid to fully drain.
Replace the transmission filter if applicable. Remove the transmission pan (if accessible) and replace the filter.
Reinstall the transmission pan and torque bolts to manufacturer specifications (typically around 8-10 Nm).

3. Inspect and Adjust Transmission Linkage

Locate the transmission linkage under the vehicle.
Check for loose, damaged, or misaligned components.
Adjust the linkage by loosening the mounting bolts and repositioning it according to specifications.
Tighten the bolts securely after adjustment.

4. Inspect Clutch (for Manual Transmission)

Check the clutch fluid level in the reservoir (if equipped) and top off if necessary.
Inspect the clutch pedal for proper engagement and free play.
Test the clutch operation by pressing the pedal and attempting to shift gears. If it does not disengage fully, consider replacing the clutch assembly.

5. Electrical and Component Check

Inspect the TCM and wiring for corrosion, damaged connectors, or shorts.
Replace any damaged wiring or connectors.
Reinstall any removed components and reconnect the battery terminal.
