Tools Required: Socket set, funnel, drain pan.
Sub-steps:
1. Remove the transmission fluid dipstick and check fluid level.
2. If low, add the correct type of transmission fluid (consult owner’s manual for specifications).
3. If the fluid is burnt or dirty, proceed to drain and replace it:
  - Locate the transmission drain plug and remove it.
  - Allow fluid to fully drain into the pan.
  - Replace the drain plug and torque it to specifications (usually around 10-15 ft-lbs).
  - Refill with new transmission fluid using a funnel.

3. Inspect and Replace Torque Converter

Tools Required: Socket set, torque wrench, transmission jack.
Sub-steps:
1. Disconnect the battery to prevent electrical shorts.
2. Remove the transmission from the vehicle:
  - Support the transmission using a jack.
  - Disconnect drive shafts and any electrical connectors.
  - Remove bolts securing the transmission to the engine and lower it carefully.
3. Remove the old torque converter:
  - Unbolt the torque converter from the flex plate.
  - Pull the converter from the transmission.
4. Install the new torque converter:
  - Align and install the new converter into the transmission.
  - Secure it to the flex plate with bolts, tightening them to specifications (approximately 30-35 ft-lbs).
5. Reinstall the transmission and reconnect all components.
