Solution

1. Preparation

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

2. Check and Replace Transmission Fluid

Tools Required: Funnel, Transmission fluid pump, Clean container
Remove the transmission fluid drain plug and allow old fluid to drain into a clean container.
Inspect the fluid for debris; if present, further investigation into the transmission may be necessary.
Replace the drain plug and refill the transmission with the correct type of fluid as per the manufacturer's specifications using a funnel.

3. Inspect and Replace Transmission Filter

Tools Required: Socket set, Torque wrench, Gasket scraper
Remove the transmission pan by loosening the bolts with a socket wrench.
Carefully detach the pan and clean the mating surfaces.
Remove the old transmission filter and replace it with a new one.
Reinstall the transmission pan with a new gasket and torque the bolts to the manufacturer's specifications.

4. Test and Replace Solenoids (if necessary)

Tools Required: Multimeter, Screwdriver set
Access the transmission control module to test the solenoids.
Use a multimeter to check the resistance of the solenoids; replace any faulty solenoids as needed.
Reconnect the transmission control module and ensure all connections are secure.
