Solution

1. Preparation

• Tools Required: Socket set, torque wrench, fluid catch pan, shop rags, O-ring pick, flashlight.
• Park the vehicle on a level surface and engage the parking brake.
• Allow the engine to cool down before starting work to avoid burns.

2. Assess and Repair the Transmission Pan

• Sub-steps:
  1. Place a fluid catch pan under the transmission pan.
  2. Remove the bolts securing the transmission pan using a socket set.
  3. Carefully lower the transmission pan and inspect for damage.
  4. If the pan is damaged, replace it with a new one.
  5. Clean the mating surface on the transmission housing to remove old gasket material.
  6. Install a new gasket or apply suitable RTV sealant for sealing.
  7. Reattach the transmission pan and torque the bolts to the manufacturer’s specifications (typically 8-10 ft-lbs).

3. Inspect and Replace the Transmission Cooler Lines

• Sub-steps:
  1. Locate the transmission cooler lines connected to the transmission.
  2. Check for any cracks or leaks in the lines.
  3. If damaged, disconnect the lines using the appropriate tools and replace with new lines.
  4. Reconnect the lines and ensure they are securely fastened.

4. Replace Seals and Gaskets

• Sub-steps:
  1. Identify any worn or damaged seals around the transmission (such as the input/output shaft seals).
  2. Remove the old seals using an O-ring pick.
  3. Lubricate the new seals with a bit of transmission fluid.
  4. Install the new seals carefully, ensuring they are seated properly.
