Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to avoid electrical shorts.

2. Check and Replace Transmission Fluid

Locate the transmission dipstick and remove it to check fluid level.
If low, add the manufacturer-recommended transmission fluid until it reaches the proper level.
If the fluid is dark or has a burnt smell, proceed to replace it.
Place a drain pan under the transmission and remove the drain plug to allow old fluid to drain completely.
Replace the drain plug and torque it to the manufacturer’s specifications (usually around 15-20 ft-lbs).
Remove the transmission pan bolts and carefully lower the pan.
Remove the old filter and replace it with a new one.
Clean the transmission pan and install a new gasket before reattaching the pan with appropriate torque.

3. Inspect and Repair Electrical Connections

Locate the transmission control module (TCM) and inspect the wiring harness for any signs of damage.
Clean or replace any corroded connectors.
Reconnect the battery and clear any error codes using an OBD-II scanner.
