Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, multimeter, transmission fluid, fluid pump.
Ensure the vehicle is on a level surface and the engine is turned off.
Disconnect the battery to prevent any electrical shorts.

2. Check and Replace Transmission Fluid

Locate the transmission dipstick and remove it.
Using a funnel, add the appropriate type of transmission fluid if low (consult the owner's manual for the correct specification).
Start the engine and let it run until it reaches operating temperature.
Shift through all gears while monitoring fluid levels, adding more fluid as necessary.
Inspect the fluid for debris or burnt smell; if contamination is present, a fluid change is recommended.

3. Inspect and Replace Transmission Filter

Remove the transmission pan by unscrewing the bolts (use a socket set).
Carefully lower the pan and drain the fluid into a pan.
Remove the old transmission filter and replace it with a new one.
Clean the transmission pan and replace the gasket.
Reinstall the pan and torque the bolts to the manufacturer's specifications.

4. Test Solenoids and Wiring

Disconnect the electrical connector from the transmission solenoids.
Use a multimeter to test the solenoids for resistance (refer to service manual for specific values).
Repair or replace any faulty wiring or solenoids as necessary.
Reconnect the solenoids and ensure connections are secure.
