Solution

1. Preparation

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

Tools Required:

OBD-II scanner
Socket set
Torque wrench
Fluid pump
Transmission jack

2. Check Transmission Fluid

Remove the transmission dipstick and wipe it clean.
Reinsert the dipstick fully, then remove it again to check the fluid level.
If low, add the manufacturer-recommended transmission fluid until the correct level is achieved.

3. Replace Transmission Filter

Locate the transmission pan and secure it with the socket set.
Carefully remove the pan and let the fluid drain into a container.
Remove the old transmission filter and install the new filter, ensuring it is properly seated.

4. Inspect and Replace Transmission Mounts

Use the transmission jack to support the transmission.
Remove bolts securing the transmission mounts.
Inspect mounts for wear or cracks; replace if necessary.
Reinstall new mounts and torque to manufacturer specifications.

5. Refill Transmission Fluid

Reinstall the transmission pan with a new gasket, ensuring a proper seal.
Fill the transmission with the appropriate fluid using a fluid pump.
Start the engine and allow it to idle; cycle through the gears to circulate the fluid.

6. Reconnect Battery and Test Drive

Reconnect the battery and clear any error codes using the OBD-II scanner.
Test drive the vehicle to ensure smooth shifting and monitor for any signs of jerking.
