Solution

1. Preparation

Tools Required: Socket set, transmission fluid dipstick, OBD-II scanner, fluid catch pan, funnel
Raise the vehicle securely on jack stands and ensure it's level.
Wear gloves and safety glasses for protection.

2. Check and Replace Transmission Fluid

Sub-steps:
1. Remove the transmission dipstick and wipe it clean.
2. Insert the dipstick back and remove it again to check fluid level.
3. If low, add the appropriate type of Toyota transmission fluid (WS) using a funnel until it reaches the correct level.
4. If the fluid appears dark or smells burnt, proceed to fluid change.

3. Change Transmission Fluid and Filter

Sub-steps:
1. Place a fluid catch pan under the transmission pan.
2. Remove the transmission pan bolts using a socket set.
3. Carefully lower the pan and allow the fluid to drain completely.
4. Remove the old transmission filter and replace it with a new one.
5. Clean the transmission pan and replace the gasket if necessary.
6. Reinstall the pan with the bolts tightened to the manufacturer’s specified torque (typically around 8-10 ft-lbs).
7. Refill the transmission with new fluid using the dipstick tube, ensuring it reaches the correct level.

4. Inspect and Adjust Linkage

Sub-steps:
1. Inspect the transmission linkage for any signs of damage or wear.
2. Adjust the linkage as needed to ensure proper engagement of gears.

5. Test Drive

Perform a test drive to confirm the issue has been resolved and monitor for any slipping.
