Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety.

2. Check Transmission Fluid

Remove the transmission dipstick and wipe it clean.
Insert the dipstick back, remove it again, and check the fluid level and condition.
- If fluid is low, top it off with the recommended transmission fluid type (usually ATF WS for Toyota).
- If fluid is dirty or burnt, proceed to change the fluid.

3. Replace Transmission Fluid and Filter

Tools Required: Socket set, transmission fluid pump, torque wrench, container for old fluid.
Locate the transmission pan and remove the pan bolts using a socket wrench.
Carefully lower the pan and drain the old fluid into a container.
Remove the old filter and replace it with a new one.
Clean the transmission pan and replace the gasket.
Reattach the pan and torque the bolts to the manufacturer’s specifications.
Refill the transmission with new fluid using a fluid pump.

4. Inspect and Replace Shift Linkage

Inspect the shift linkage for damage or misalignment.
If damaged, disconnect and remove the faulty linkage.
Install the new shift linkage, ensuring it is properly aligned and secured.

5. Test Transmission Solenoids

Tools Required: Multimeter.
Disconnect the wiring harness from each solenoid.
Use a multimeter to check the resistance of each solenoid according to the manufacturer's specifications.
Replace any faulty solenoids.
