Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent electrical issues.

2. Check and Change Transmission Fluid

Sub-steps:
1. Remove the transmission dipstick, if equipped, and check the fluid level.
2. If fluid is low, add the recommended transmission fluid type (Mercon LV) until it reaches the proper level.
3. If fluid is burnt or contaminated, proceed with a full fluid change:
  - Remove the transmission pan by unscrewing the bolts and draining old fluid into a catch pan.
  - Replace the transmission filter if applicable.
  - Reinstall the pan with a new gasket and torque bolts to manufacturer specifications (typically around 12-15 ft-lbs).
  - Refill with new Mercon LV fluid through the dipstick tube.

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

Sub-steps:
1. Locate the TCM, usually found near the transmission or under the dashboard.
2. Disconnect the electrical connectors from the TCM.
3. Remove the TCM from its mounting bracket.
4. Install the new TCM by reversing the removal steps.
5. Reconnect the battery and reprogram the TCM using a diagnostic tool.

4. Inspect Transmission Mounts

Sub-steps:
1. Lift the vehicle securely on jack stands.
2. Visually inspect the transmission mounts for cracks or deterioration.
3. If mounts are damaged, remove the old mounts and replace them with new OEM mounts.
4. Torque the mount bolts to the manufacturer's specifications.
