Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Gather all necessary tools and parts.
Disconnect the battery to prevent electrical shorts.

2. Drain Transmission Fluid

Place a drain pan under the transmission.
Remove the transmission drain plug and let the fluid drain completely.
Inspect the drained fluid for metal particles or debris that could indicate internal damage.

3. Remove Transmission Pan

Remove the bolts securing the transmission pan using a socket set.
Carefully lower the pan and clean the mating surfaces.
Inspect the pan for metal shavings or debris.

4. Inspect Internal Components

Check the condition of the gears, syncros, and bearings for signs of wear or damage.
If any components are damaged, they will need to be replaced.

5. Replace Transmission Fluid and Reinstall Components

Install a new gasket on the transmission pan.
Reattach the transmission pan and torque bolts to the manufacturer's specifications.
Refill the transmission with the recommended fluid type and amount.

6. Test Drive

Reconnect the battery.
Start the vehicle and let it reach operating temperature.
Perform a test drive to ensure the grinding noise has been resolved.
