Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety during repairs.
Allow the vehicle to cool if it has been running.

2. Check and Replace Transmission Fluid

Sub-steps:
1. Raise the vehicle using a jack and secure with jack stands.
2. Locate the transmission fluid dipstick; remove it and wipe it clean.
3. Insert the dipstick back into the tube and remove it again to check the fluid level.
4. If low, add the manufacturer's recommended transmission fluid through the dipstick tube.
5. If fluid is burnt or dirty, drain the old fluid completely using a fluid pump.
Tools Required:
- Fluid pump
- Transmission fluid (consult owner’s manual for specifications)

3. Inspect and Replace Transmission Filter

Sub-steps:
1. Remove the transmission pan by unscrewing the bolts (use a torque wrench for reinstallation).
2. Carefully lower the pan and remove the old filter.
3. Install the new filter and clean the mating surface before reinstalling the pan.
4. Reattach the pan with the specified torque settings.
Tools Required:
- Socket set
- Torque wrench
- Gasket scraper

4. Test Transmission Solenoids

Sub-steps:
1. Locate the transmission solenoids based on the vehicle's service manual.
2. Disconnect the electrical connectors from the solenoids.
3. Use a multimeter to check for continuity and resistance as per specifications.
4. Replace any faulty solenoids identified during testing.
Tools Required:
- Multimeter
- Basic hand tools
