Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a level surface.
Disconnect the battery to prevent electrical shorts.

Tools Required:

OBD-II scanner
Socket set
Torque wrench
Transmission fluid pump
Multimeter
Fluid catch pan

2. Inspect and Replace Transmission Fluid

Raise the vehicle using a jack and secure it with jack stands.
Locate the transmission pan; place a fluid catch pan underneath it.
Remove the transmission pan bolts using a socket set.
Carefully lower the pan to drain the old fluid; inspect the pan for metal shavings or debris.
Clean the pan and replace the transmission filter if applicable.
Reattach the transmission pan, ensuring to torque bolts to manufacturer specifications (usually around 10-12 ft-lbs).
Fill the transmission with the appropriate fluid type (check owner’s manual for specifications) using a fluid pump.

3. Inspect and Repair Wiring and Connectors

Locate the transmission control module (TCM) and its associated wiring harness.
Visually inspect the wiring for any signs of wear, fraying, or damage.
Use a multimeter to check for continuity in the wiring.
Repair or replace any damaged wires or connectors as needed.

4. Reconnect Battery and Test

Reconnect the battery terminals securely.
Start the vehicle and let it idle for a few minutes.
Perform a test drive to confirm if the transmission operates smoothly and if the check engine light remains off.
