Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, transmission fluid dipstick, fluid pump.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery negative terminal to ensure safety.

2. Check and Change Transmission Fluid

Sub-steps:
1. Remove the transmission dipstick and check the fluid level.
2. If low, use a fluid pump to add the appropriate type of transmission fluid (consult owner's manual for specifications).
3. If the fluid is dirty or burnt, proceed to drain the transmission fluid.
  - Place a drain pan under the transmission pan.
  - Remove the transmission pan bolts using a socket wrench.
  - Carefully lower the pan and allow fluid to drain completely.
4. Replace the filter if applicable, following the manufacturer's specifications.
5. Clean the pan and magnet (if present) before reinstallation.
6. Reinstall the pan with new gasket and torque bolts to manufacturer specifications.

3. Inspect and Replace Transmission Mounts

Sub-steps:
1. Visually inspect the transmission mounts for cracks or excessive wear.
2. To replace, support the transmission with a jack.
3. Remove the bolts securing the old mounts using a socket set.
4. Install new mounts and torque to specifications.
5. Lower the transmission and ensure proper alignment.

4. Reprogram or Replace TCM

Sub-steps:
1. If diagnostics indicate TCM issues, attempt to reprogram the module using an OBD-II scanner with programming capabilities.
2. If reprogramming fails, replace the TCM with a compatible unit.
3. Follow specific installation instructions and ensure all connectors are secure.
