1. Preparation

Gather Tools and Parts: Ensure you have an OBD-II scanner, socket set, torque wrench, fluid pump, and replacement transmission fluid.
Safety Precautions: Disconnect the battery to prevent electrical shorts while working on the vehicle.

2. Fluid Change

Drain Transmission Fluid:
- Place a drain pan under the transmission, remove the drain plug or pan bolts, and allow the fluid to completely drain.
Replace Transmission Filter:
- Remove the transmission pan and filter. Install a new filter and gasket.
Refill with New Transmission Fluid:
- Using a fluid pump, refill the transmission with the manufacturer-recommended fluid type (check the owner’s manual for specifications).

3. Torque Converter Inspection

Remove Transmission Access Cover:
- If necessary, remove components obstructing access to the torque converter.
Inspect Torque Converter:
- Check for any signs of wear or damage. If defective, replace the torque converter.

4. Transmission Mounts Replacement (if needed)

Remove Old Mounts:
- Support the transmission with a jack, then remove the bolts securing the mounts to the chassis and transmission.
Install New Mounts:
- Position the new mounts and bolt them securely, adhering to the manufacturer’s torque specifications.
