Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety while working on electrical components.

2. Fluid Change

Tools Required: Socket set, transmission fluid pump, drain pan, funnel, torque wrench.
Remove the transmission pan by unbolting it carefully to avoid damaging the gasket.
Allow the old transmission fluid to completely drain into a pan.
Replace the transmission filter if applicable.
Reinstall the transmission pan with a new gasket, torquing bolts to the manufacturer’s specifications.

3. Fluid Replacement

Using a transmission fluid pump, fill the transmission with the recommended type of fluid until it reaches the proper level as indicated on the dipstick.
Start the engine and allow it to idle; check the fluid level again and top off if necessary.

4. Torque Converter Inspection

Tools Required: Torque wrench, possibly a transmission jack.
Remove the transmission if necessary to access the torque converter.
Inspect the torque converter for wear or damage; replace if found defective.
Ensure that the torque converter is properly seated on the flywheel before reinstallation.

5. Software Update

Reconnect the battery and use a diagnostic tool to check for available software updates for the TCM.
Follow the manufacturer's instructions to perform the update if available.
