2. Locate the shift linkage connected to the transmission.
3. Inspect for any signs of wear, misalignment, or damage.
4. Adjust or replace components as needed to ensure proper alignment.

4. Check Transmission Control Module (TCM)

Sub-steps:
1. Disconnect the battery to ensure safety.
2. Locate the TCM, usually near the transmission or under the dashboard.
3. Inspect the TCM connectors for corrosion or damage.
4. Reconnect or replace the TCM if necessary.

5. Clutch Inspection (if applicable)

Sub-steps:
1. If a manual transmission, inspect the clutch pedal for free play.
