Solution

1. Preparation

Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the negative battery terminal for safety.
Gather tools: socket set, torque wrench, transmission fluid, and OBD-II scanner.

2. Check Transmission Fluid

Sub-step 1: Locate the transmission dipstick and remove it.
Sub-step 2: Wipe it clean and reinsert to check the fluid level.
Sub-step 3: Inspect the fluid for color (should be red or pink) and smell (burnt odor indicates degradation).
Sub-step 4: If low, add the manufacturer-recommended transmission fluid to the appropriate level.

3. Inspect Transmission Mounts

Sub-step 1: Raise the vehicle using jack stands for access.
Sub-step 2: Visually inspect the transmission mounts for cracks, tears, or excessive wear.
Sub-step 3: If damaged, remove the old mounts using a socket set and replace them with new mounts, torquing to manufacturer specifications.

4. Adjust Shifter Linkage

Sub-step 1: Locate the shifter linkage under the vehicle.
Sub-step 2: Check for any loose or disconnected components.
Sub-step 3: If misaligned, adjust the linkage and ensure it is securely fastened.

5. Testing After Repair

Sub-step 1: Reconnect the negative battery terminal.
Sub-step 2: Start the engine and test the shifting through all gears to ensure the noise is resolved.
Sub-step 3: Conduct a test drive to confirm that the issue does not reoccur.
