Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and securely raise it using jack stands.

2. Fluid Change

Step 1: Drain the transmission fluid.
- Locate the transmission drain plug and use a socket set to remove it.
- Allow fluid to drain completely into a drain pan.
Step 2: Replace the transmission filter.
- Remove the transmission pan by unscrewing the bolts with a ratchet and socket.
- Replace the old filter with a new one, ensuring the rubber O-ring is seated correctly.
Step 3: Reinstall the transmission pan.
- Clean the pan and apply a new gasket if needed. Torque the bolts to the manufacturer's specifications (typically around 8-10 Nm).

3. Torque Converter Replacement (if diagnosed as faulty)

Step 1: Remove the transmission.
- Disconnect the battery and remove the starter motor if necessary.
- Detach the drive shafts and any electrical connectors attached to the transmission.
- Support the transmission with a jack and remove the mounting bolts.
Step 2: Remove the torque converter.
- Once the transmission is removed, unbolt the torque converter from the flex plate.
- Replace the old torque converter with a new one, ensuring it is properly aligned with the transmission input shaft.
Step 3: Reinstall the transmission.
- Reverse the removal steps, ensuring all components are secured and connections are reattached.
