Solution

1. Preparation

Tools Required: Jack stands, socket set, OBD-II scanner, torque wrench, transmission fluid.
Ensure the vehicle is on a flat surface and the engine is off.
Disconnect the battery to prevent any electrical issues.

2. Check Transmission Fluid

Locate the transmission dipstick.
Pull out the dipstick, wipe it clean, and reinsert it.
Remove the dipstick again and check the fluid level.
If low, add the appropriate type of transmission fluid (check owner’s manual for specifications).
Inspect fluid condition; it should be red and clear. If it's dark or has a burnt smell, a fluid change is necessary.

3. Inspect Transmission and Linkage

Raise the vehicle using jack stands.
Visually inspect under the vehicle for any signs of leaks or damage to the transmission casing.
Check the gear linkage for proper attachment and alignment.
Adjust or replace the linkage if misaligned or damaged.

4. Scan for Error Codes

Connect the OBD-II scanner to the vehicle’s diagnostic port.
Turn the ignition to the "ON" position without starting the engine.
Review any stored codes, particularly those related to the transmission or TCM.
Clear codes and conduct a short test drive to see if any codes reappear.

5. Examine and Replace TCM (if applicable)

If error codes indicate a TCM issue, locate the TCM (usually found near the transmission or under the dashboard).
Disconnect the electrical connectors and remove the TCM.
Replace it with a new or refurbished unit, and reconnect the connectors.
