Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the vehicle battery to ensure safety while working on electrical components.
Raise the vehicle using a jack and secure it on jack stands to access the transmission.

2. Check and Replace Transmission Fluid

Tools Required: Transmission funnel, catch pan, socket set.
Remove the transmission fluid drain plug and let the fluid drain completely into the catch pan.
Replace the drain plug and refill the transmission with new, manufacturer-recommended fluid using the transmission funnel until it reaches the proper level.
Check for leaks after refilling.

3. Replace Transmission Filter

Tools Required: Socket set, screwdriver, gasket scraper, new transmission filter, and gasket.
Remove the transmission pan by unscrewing the bolts securing it and carefully pry it off.
Take out the old transmission filter and install the new one, ensuring it fits snugly.
Clean the transmission pan and mating surface, then replace the gasket and reattach the pan using the correct torque specification for the bolts.

4. Inspect and Replace Transmission Solenoids (if necessary)

Tools Required: Socket set, multimeter, replacement solenoids.
Remove the necessary components to access the transmission solenoids.
Disconnect the electrical connectors and remove the solenoids.
Test the solenoids with a multimeter to verify functionality; replace any faulty solenoids with new units.
Reinstall components in the reverse order, ensuring all connections are secure.
