Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety while working on the electrical system.

2. Check and Replace Transmission Fluid

Tools Required: Fluid pump, funnel, socket set
Locate the transmission dipstick or fill plug.
Remove the dipstick or plug and check fluid level and condition.
If fluid is low or contaminated, drain the old transmission fluid using the drain plug.
Replace with manufacturer-recommended ATF (Automatic Transmission Fluid).
Recheck fluid level after filling.

3. Replace Transmission Filter

Tools Required: Socket set, screwdriver, gasket scraper
Remove the transmission pan by unbolting it, ensuring to catch any leaking fluid in a pan.
Take out the old transmission filter.
Install the new filter, ensuring it is securely in place.
Clean the pan and replace the gasket if needed.
Reinstall the transmission pan and torque bolts to the manufacturer's specifications.

4. Inspect and Replace Solenoids (if necessary)

Tools Required: Multimeter, socket set
Access the transmission solenoids (may require removal of the valve body).
Test each solenoid for resistance using a multimeter.
If any solenoid is faulty, replace it with a new one.
Reassemble the valve body and transmission as needed.
