Solution

1. Preparation

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

2. Check and Replace Transmission Fluid

Sub-steps:
1. Locate the transmission dipstick and remove it.
2. Wipe the dipstick clean and reinsert it to check the fluid level.
3. If low, add the recommended type of transmission fluid (typically Toyota ATF WS).
4. If fluid is burnt or contaminated, proceed to drain and replace the fluid.
Tools Required: Transmission funnel, drain pan.

3. Replace Transmission Filter

Sub-steps:
1. Raise the vehicle securely on jack stands.
2. Remove the transmission pan bolts and carefully lower the pan.
3. Replace the old transmission filter with a new one.
4. Clean the transmission pan and replace the gasket before reinstalling.
Tools Required: Socket set, torque wrench, gasket scraper.

4. Inspect and Repair Transmission Linkage

Sub-steps:
1. Visually inspect the linkage and cables for damage or misalignment.
2. Adjust or replace any damaged components.
3. Ensure proper alignment and secure connections.
Tools Required: Wrenches, pliers.

5. Test and Replace Solenoids (if necessary)

Sub-steps:
1. Use a multimeter to test the resistance of each solenoid according to the service manual specifications.
2. Replace any solenoid that is out of specification.
Tools Required: Multimeter, socket set.
