Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the battery for safety.

2. Check and Replace Transmission Fluid

Step 1: Remove the transmission dipstick to check fluid level.
- Tool Required: None
Step 2: If low, add the recommended type of transmission fluid (Toyota ATF WS).
Step 3: If fluid is burnt or discolored, drain the old fluid using a drain pan.
Step 4: Replace the transmission filter (if applicable) by removing the transmission pan.
- Tool Required: Socket set
Step 5: Reinstall the pan with a new gasket, tightening bolts to the manufacturer’s torque specifications (usually around 7-10 ft-lbs).
Step 6: Refill the transmission with new fluid through the dipstick tube.

3. Inspect and Repair Transmission Components

Step 1: If slipping persists, remove the transmission pan to inspect internal components.
- Tool Required: Socket set
Step 2: Examine the clutch packs and bands for wear and damage, replacing as necessary.
Step 3: Replace any damaged seals or gaskets found during inspection.
Step 4: Reassemble the transmission pan and refill with fluid.
