Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the negative battery terminal to ensure safety while working on electrical components.

2. Inspect and Change Transmission Fluid

Tools Required: Socket set, fluid pump, catch pan.
Remove the transmission fill plug and check the fluid level; add fluid if low.
If fluid is dirty or burnt, drain the old fluid by removing the drain plug.
Replace with manufacturer-recommended transmission fluid (check owner’s manual for specifications).
Reinstall the drain plug and fill the transmission with new fluid using a fluid pump through the fill hole.

3. Replace Transmission Filter

Tools Required: Socket set, wrench, transmission filter kit.
Remove the transmission pan by unscrewing all bolts; use a catch pan to collect any remaining fluid.
Remove the old transmission filter and replace it with a new one from the kit.
Clean the pan and replace the gasket to prevent leaks before reattaching.

4. Inspect and Repair Electrical Components

Tools Required: Multimeter, wiring diagram.
Check the harness and wiring for any signs of damage or wear.
Use a multimeter to test the transmission control module for proper voltage and ground.
Repair or replace any damaged wiring or connectors.
