Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to ensure safety.

2. Check and Replace Transmission Fluid

Sub-steps:
1. Locate the transmission dipstick and remove it.
2. Wipe it clean and reinsert it, then remove it again to check the fluid level.
3. If the fluid is low or burnt, drain the transmission fluid using a fluid pump.
4. Replace with fresh transmission fluid specified by the manufacturer (typically ATF WS for Toyota).
5. Recheck the fluid level after refilling.

3. Inspect and Adjust Transmission Linkage

Sub-steps:
1. Locate the transmission linkage outside the transmission.
2. Visually inspect for any wear, bending, or misalignment.
3. Adjust the linkage according to the service manual specifications.
4. Tighten all connections securely.

4. Replace or Repair Faulty Components

Sub-steps:
1. If error codes indicate a faulty solenoid, remove the transmission pan.
2. Replace the affected solenoid(s) as per manufacturer specifications.
3. Reinstall the pan with a new gasket and torque bolts to the specified value (usually around 10-12 ft-lbs).
4. Reconnect the battery.
