Solution

1. Preparation

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

2. Check and Replace Transmission Fluid

Remove the transmission dipstick and check fluid level and condition.
If fluid is low, add the recommended Toyota ATF type fluid to the proper level.
If fluid is burnt or discolored, proceed to change the fluid.
- Sub-steps:
  1. Place a drain pan under the transmission pan.
  2. Remove the transmission pan bolts using a socket wrench.
  3. Carefully lower the pan to drain the old fluid.
  4. Remove the old filter and replace it with a new one.
  5. Clean the transmission pan and magnet, then reinstall it.
  6. Refill with new transmission fluid through the dipstick tube.

3. Inspect and Replace Transmission Filter (if necessary)

Ensure the vehicle is secure and on a level surface.
Remove the transmission pan (as detailed above).
Replace the transmission filter if it appears clogged or damaged.
Sub-steps:
1. Remove the old filter and dispose of it properly.
2. Install the new filter, ensuring it is seated correctly.
3. Reinstall the transmission pan and torque bolts to manufacturer specifications.

4. Test Transmission Solenoids

Reconnect the battery cable.
Use a multimeter to check the resistance of each solenoid.
- Sub-steps:
  1. Locate the solenoids according to the repair manual.
  2. Disconnect the electrical connectors.
  3. Measure resistance and compare with specifications.
  4. Replace any solenoids that are out of specification.
