Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and secured with wheel chocks.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Check Transmission Fluid

Remove the transmission dipstick and wipe it clean.
Insert the dipstick back into the tube and remove it again to check the fluid level and condition.
If low, add the manufacturer-recommended transmission fluid.

3. Inspect Transmission Linkage

Locate the transmission linkage connected to the gear shifter.
Inspect for any signs of damage or disconnection.
If damaged, replace the linkage with a new one.

4. Address Electrical Issues

Reconnect the battery terminal.
Use a multimeter to check the voltage at the transmission control module.
If the voltage is low or there are faults, repair or replace the wiring as needed.

5. Repair or Replace Transmission Components

If the transmission fluid is contaminated, consider a fluid change:
- Drain the old fluid from the transmission pan.
- Replace the transmission filter (if applicable).
- Refill with new transmission fluid to the recommended level.
If internal damage is suspected, consult a professional for a complete transmission rebuild or replacement.
