Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface, engage the parking brake, and disconnect the battery to prevent electrical shorts.

2. Check and Replace Transmission Fluid

Tools Required: Transmission fluid pump, socket set, fluid catch pan.
Remove the transmission fluid pan using a socket set.
Drain the old fluid into a catch pan and inspect it for metal shavings or debris.
Replace the filter if applicable.
Refill with manufacturer-recommended transmission fluid, ensuring the correct level is reached.

3. Inspect and Replace Transmission Control Module (if necessary)

Tools Required: OBD-II scanner, torque wrench.
Connect the OBD-II scanner and check for any error codes related to the TCM.
If codes indicate a TCM issue, replace it following the manufacturer's specific torque values and procedures.
Reconnect the battery and clear any error codes using the scanner.

4. Check Engine and Transmission Mounts

Tools Required: Jack and jack stands, socket set.
Lift the vehicle and support it with jack stands.
