Solution

1. Preparation

Tools Required: OBD-II scanner, torque wrench, socket set, jack stands, transmission fluid, funnel.
Safety Warnings: Ensure the vehicle is parked on a level surface and set the parking brake. Disconnect the negative battery terminal before starting work.

2. Remove Transmission Pan

Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Place a drain pan under the transmission pan to catch fluid.
3. Remove the bolts securing the transmission pan using a socket wrench.
4. Carefully detach the pan, allowing fluid to drain completely. Inspect the magnet for metal shavings.

3. Inspect Torque Converter

Sub-steps:
1. Access the torque converter through the transmission bell housing or by removing the transmission (if necessary).
2. Check for any visible damage or signs of wear on the torque converter.
3. Spin the torque converter manually to assess for smooth operation or binding.

4. Replace or Repair as Needed

Sub-steps:
1. If the torque converter is faulty, remove it by disconnecting the retaining bolts and any electrical connections.
2. Install the new or rebuilt torque converter, ensuring proper alignment with the engine and transmission.
3. Reattach all connections and secure with appropriate torque specifications.
4. Reinstall the transmission pan with a new gasket and torque the bolts to manufacturer specifications.

5. Refill Transmission Fluid

Sub-steps:
1. Use a funnel to refill the transmission with the correct type and quantity of fluid as specified in the owner’s manual.
2. Start the engine and let it idle; shift through all gears to circulate the fluid.
3. Check the fluid level using the dipstick, adding more fluid if necessary.
