Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Tools Required: OBD-II scanner, socket set, torque wrench, transmission jack, fluid pump.

2. Check and Replace Transmission Fluid

Sub-steps:
1. Remove the transmission fluid dipstick (if applicable) and check fluid level.
2. If low, add the recommended type of transmission fluid (typically ATF WS for Toyota).
3. If the fluid is dark or burnt, proceed to replace it:
  - Locate and remove the transmission pan bolts with a socket set.
  - Carefully lower the transmission pan using a transmission jack.
  - Allow old fluid to drain completely into a suitable container.
  - Clean the transmission pan and magnet (if equipped) to remove debris.
  - Replace the transmission filter if necessary.
  - Reinstall the pan with a new gasket, torque bolts to specifications (typically 8-10 ft-lbs).
  - Refill the transmission with new fluid using a fluid pump.

3. Inspect and Repair Transmission Components

Sub-steps:
1. Check for damaged or worn components in the transmission linkage; replace any damaged parts.
2. If the fluid pressure test indicated low pressure, inspect the pump and valve body for faults.
3. If necessary, remove the transmission for a more thorough inspection of internal components.
4. Replace any worn clutches or bands and reassemble, ensuring all gaskets and seals are replaced.
