Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, fluid catch pan, and rags.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the battery to prevent electrical shorts.

2. Check and Refill Transmission Fluid

Remove the transmission dipstick and wipe it clean.
Reinsert the dipstick and remove it again to check the fluid level.
If low, add the manufacturer-recommended transmission fluid through the dipstick tube.
Start the engine, shift through the gears with the brake pedal pressed, and recheck the fluid level.

3. Inspect Gear Shift Linkage

Locate the gear shift linkage under the vehicle.
Inspect for any signs of wear, damage, or disconnection.
If damaged, replace the linkage components using a socket set.
Ensure the linkage is properly adjusted and secured.

4. Check Transmission Control Module (TCM)

Reconnect the battery and use the OBD-II scanner to check for TCM error codes.
If present, follow manufacturer instructions to reset the TCM or replace it if faulty.
Clear the error codes and test drive the vehicle.

5. Inspect Clutch System (for Manual Transmissions)

Check the clutch fluid level in the reservoir; refill if low.
Inspect the clutch slave and master cylinders for leaks.
If leaks are present, replace the defective components and bleed the clutch system.
