Solution

1. Preparation

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

2. Transmission Fluid Change

Sub-steps:
1. Remove the transmission fluid drain plug using a socket set and drain the old fluid into a pan.
2. Replace the drain plug with a new gasket; torque to manufacturer's specifications.
3. Remove the transmission fill plug and use a funnel to add new transmission fluid (refer to owner's manual for the specific type).
4. Start the engine and let it run for a few minutes; check fluid levels and add more if necessary.

3. Inspect and Replace Transmission Filter

Sub-steps:
1. Remove the transmission pan by unscrewing the bolts with a socket set.
2. Carefully detach the pan and clean the mating surfaces.
3. Remove the old filter and replace it with a new one.
4. Reinstall the transmission pan with a new gasket, torquing to specifications.

4. Check and Test Transmission Solenoids

Sub-steps:
1. Locate the transmission solenoids (refer to the service manual for exact location).
2. Disconnect the electrical connectors from the solenoids.
3. Use a multimeter to test the resistance of each solenoid; replace any that are out of specification.
4. Reconnect the solenoids and secure any connectors.

5. Reconnect Battery and Test Drive

Sub-steps:
1. Reconnect the battery terminals.
2. Start the vehicle and allow it to reach operating temperature.
3. Perform a test drive to assess the engagement and shifting quality.
