Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative battery terminal for safety.

2. Fluid Change

Tools Required: Socket set, transmission fluid pump, new transmission fluid, fluid catch pan.
Remove the transmission drain plug using a socket set and allow old fluid to completely drain into the catch pan.
Replace the drain plug and torque it to the manufacturer's specifications (consult service manual for exact torque value).
Using a fluid pump, fill the transmission with new fluid through the fill port until it reaches the correct level.

3. Electrical Inspection

Tools Required: Multimeter.
Reconnect the negative battery terminal and start the engine.
Use a multimeter to check the voltage at the transmission control module (TCM). It should match the specifications in the service manual.
Repair or replace any faulty connectors or wiring as needed.

4. Solenoid Replacement (if applicable)

Tools Required: Socket set, torque wrench.
Remove the transmission pan to access the solenoids.
Disconnect the electrical connectors from the solenoids and remove the retaining bolts.
Replace with new solenoids, ensuring they are seated properly and torque the bolts to specifications.
Reinstall the transmission pan with a new gasket and torque to manufacturer specifications.

5. Reassembly and Test

Reconnect all components and ensure all connections are secure.
Perform a road test to confirm the issue is resolved. Pay attention to shifting behavior and any warning lights.
