Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety.
Safety glasses and gloves should be worn.

2. Check and Replace Transmission Fluid

Tools Required: Transmission fluid pump, funnel, drain pan.
Remove the transmission drain plug and let the old fluid drain completely into the drain pan.
Inspect the old fluid for metal shavings or burnt odor; if present, further transmission inspection may be needed.
Reinstall the drain plug with the correct torque specifications (usually around 15-20 ft-lbs).
Use the fluid pump to refill the transmission with the manufacturer-recommended fluid type.

3. Replace Transmission Filter (if applicable)

Tools Required: Socket set, screwdriver, new transmission filter, new gasket.
Remove the transmission pan bolts using the socket set and carefully take off the pan.
Remove the old filter and replace it with a new one, ensuring the gasket is properly seated.
Clean the pan and reattach it with the proper torque specifications.

4. Reset Transmission Control Module (if applicable)

Tools Required: OBD-II scanner.
Reconnect the battery terminal.
Use the OBD-II scanner to reset the transmission control module settings.
Test drive the vehicle to ensure proper shifting and functionality.
