Remove the transmission dipstick (if equipped).
Wipe it clean, reinsert, and remove it again to check the fluid level.
If low, add the manufacturer-recommended transmission fluid until it reaches the proper level.

3. Inspect Transmission Control Module (TCM)

Locate the TCM, usually found near the transmission or under the dashboard.
Disconnect the TCM connector and inspect for corrosion or bent pins.
Reconnect it securely; if damaged, consider replacing the TCM.

4. Examine Gear Shift Linkage

Inspect the gear shift linkage for any signs of wear or misalignment.
Adjust or replace the linkage as necessary to ensure proper engagement.

5. Reconnect Battery and Test

Reconnect the battery and start the vehicle.
Shift through the gears to check if the issue persists.

6. Clear Error Codes

Use the OBD-II scanner to clear any error codes related to the transmission.
Test drive the vehicle to ensure all systems are operating correctly.
