Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the negative battery terminal to ensure safety.
Allow the vehicle to cool down before starting work.

2. Change Transmission Fluid and Filter

Sub-steps:
1. Raise the vehicle using a jack and secure it on jack stands.
2. Place a drain pan under the transmission pan.
3. Remove the transmission pan bolts and carefully lower the pan to drain the fluid.
4. Replace the transmission filter inside the pan.
5. Clean the pan and replace the pan gasket. Reattach the pan with bolts tightened to the manufacturer's torque specifications.
6. Refill the transmission with the appropriate type of fluid (consult the owner’s manual for specifications).

3. Torque Converter Replacement (if necessary)

Sub-steps:
1. Remove any components obstructing access to the torque converter (e.g., transmission cooling lines, starter motor).
2. Disconnect the torque converter from the flex plate by removing the bolts.
3. Remove the transmission from the vehicle by unbolting it from the engine and supporting it with a transmission jack.
4. Pull out the torque converter from the transmission.
5. Install the new torque converter, aligning it properly with the pump and flex plate.
6. Reattach the transmission to the engine, ensuring all bolts are torqued to specifications.

4. Reconnect Battery

Reconnect the negative battery terminal and check for secure connections.
