Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and secure it with jack stands.
Disconnect the negative battery terminal to prevent electrical issues.

2. Drain Transmission Fluid

Tools Required: Socket set, drain pan
Place a drain pan under the transmission fluid pan.
Remove the transmission pan bolts and carefully lower the pan to drain the fluid.
Inspect the fluid for metal shavings or debris, which indicates internal wear.

3. Inspect and Replace Worn Components

Tools Required: Torque wrench, socket set, screwdrivers
Remove the transmission pan completely and inspect the filter for blockages.
Replace the transmission filter if clogged or damaged; use new gaskets when reinstalling the pan.
If internal components (like gears or synchronizers) are worn, consult the service manual for detailed disassembly instructions and replace necessary parts.

4. Reassemble and Refill Transmission

Reinstall the transmission pan with new gaskets, tightening bolts to the specified torque from the service manual.
Tools Required: Torque wrench
Refill the transmission with the correct type of transmission fluid as specified in the owner's manual.

5. Conduct Final Checks

Reconnect the negative battery terminal.
Start the engine and let it idle while checking for leaks.
Perform a road test to ensure the grinding noise has been resolved.
