Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, multimeter, transmission fluid, funnel, rags.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety while working on electrical components.

2. Check and Replace Transmission Fluid

Sub-steps:
1. Locate the transmission dipstick or fill plug.
2. Remove the dipstick and wipe it clean.
3. Reinsert the dipstick and remove it again to check fluid level; add fluid if low.
4. If the fluid appears discolored or burnt, proceed to drain and replace it.
5. Place a drain pan under the transmission and remove the drain plug to drain the old fluid completely.
6. Replace the drain plug and torque it to the manufacturer’s specifications (typically around 15-20 ft-lbs).
7. Remove the fill plug and use a funnel to add new transmission fluid, ensuring it meets Toyota specifications (usually Toyota ATF WS).
8. Reinstall the fill plug and check the fluid level again.

3. Inspect and Replace Transmission Filter

Sub-steps:
1. Remove the transmission pan by loosening the bolts with a socket set.
2. Carefully lower the pan and drain any remaining fluid into a container.
3. Remove the old filter and install the new filter, ensuring it is seated properly.
4. Clean the pan and the mating surface on the transmission.
5. Reinstall the transmission pan with a new gasket and torque the bolts to the manufacturer's specifications.

4. Test Transmission Solenoids

Sub-steps:
1. Locate the transmission solenoids (refer to service manual for exact location).
2. Disconnect the wiring harness from the solenoids.
3. Using a multimeter, check the resistance of each solenoid; compare readings with specifications in the service manual.
4. Replace any faulty solenoids.
