Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and securely lifted if necessary.
Disconnect the battery to prevent electrical shorts.

2. Fluid Inspection and Replacement

Check Fluid Level:
- Remove the transmission dipstick (if applicable) and wipe clean.
- Reinsert and remove to check the fluid level; top up with manufacturer-recommended transmission fluid if low.
Fluid Change:
- Place a drain pan under the transmission pan.
- Remove the transmission pan bolts and carefully lower the pan to drain the fluid.
- Replace the filter if applicable, ensuring the new filter aligns properly.
- Clean the pan and reattach it with new gasket material or an OEM gasket.
- Refill the transmission with fresh fluid according to the manufacturer’s specifications.

3. Torque Converter Replacement (if necessary)

Removal:
- Disconnect the transmission cooler lines.
- Remove the transmission from the engine by unbolting it from the engine block and supporting it with a transmission jack.
- Disconnect any electrical connectors related to the torque converter.
- Remove the torque converter from the input shaft.
Installation:
- Install the new torque converter onto the input shaft of the transmission.
- Ensure it is seated properly and aligned.
- Reinstall the transmission, reconnecting all lines and electrical connections.
- Refill the transmission fluid to the appropriate level.
