Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the negative terminal of the battery to prevent any electrical shorts.

2. Check and Replace Transmission Fluid

Locate the transmission dipstick and remove it to check fluid level.
If fluid is low or burnt, drain the old fluid using a transmission fluid pump.
Replace with the manufacturer-recommended transmission fluid type.
Recheck the fluid level after refilling.

3. Inspect and Repair Gear Shifter Linkage

Remove any console covers to access the gear shifter mechanism.
Inspect the linkage for any signs of wear or disconnection.
If damaged, replace the gear shift cable or linkage as necessary.
Reassemble the console cover once repairs are complete.

4. Address Fault Codes

If any fault codes were retrieved, use the appropriate repair manual to address the specific issues indicated.
This may involve replacing sensors, solenoids, or other transmission components as necessary.

5. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the vehicle and check if the issue is resolved by attempting to shift into gear.
