Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent electrical shorts during repairs.

2. Check and Replace Transmission Fluid

Sub-steps:
1. Locate the transmission dipstick and remove it.
2. Clean the dipstick and reinsert it to check fluid level.
3. If fluid is low, add the correct type of transmission fluid (Toyota WS) through the dipstick tube.
4. If fluid is dirty or burnt, drain the transmission fluid using a drain pan.
5. Replace the old fluid with new fluid while ensuring the correct volume is added.

Tools Required:

Transmission fluid pump
Drain pan
Funnel

3. Inspect and Replace Transmission Filter

Sub-steps:
1. Remove the transmission pan by unscrewing the bolts; ensure to have a drain pan underneath to catch any fluid.
2. Remove the old transmission filter and discard it.
3. Clean the pan and magnet thoroughly to remove any debris.
4. Install the new transmission filter, ensuring it fits snugly.
5. Reattach the transmission pan with a new gasket and torque bolts to manufacturer specifications.

Tools Required:

Socket set
Torque wrench

4. Check and Repair Transmission Linkage

Sub-steps:
1. Inspect the transmission linkage for any signs of damage or misalignment.
2. Adjust the linkage if necessary to ensure proper engagement.
