Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and engage the parking brake.
Disconnect the battery to prevent electrical shorts.

2. Fluid Change

Sub-steps:
1. Remove the transmission pan bolts using a socket wrench.
2. Carefully lower the pan and drain old fluid into a container.
3. Replace the transmission filter if applicable, ensuring the new filter aligns correctly.
4. Clean the transmission pan and magnet of any debris.
5. Reattach the pan and tighten bolts to manufacturer specifications (typically 12-15 ft-lbs).

3. Electrical Inspection

Sub-steps:
1. Inspect and clean the transmission wiring harness connectors.
2. Use a multimeter to check the resistance of the solenoids; refer to service manual specifications.
3. Replace any faulty solenoids as necessary by unbolting them and detaching the connectors.

4. Test Drive

Sub-steps:
1. Reconnect the battery and start the vehicle.
2. Allow the vehicle to warm up and shift through all gears while stationary.
3. Perform a road test to confirm the resolution of symptoms.
