Solution

1. Preparation

Tools Needed: Socket set, torque wrench, fluid catch pan, transmission fluid, rags.
Ensure the vehicle is on a level surface and securely lifted using jack stands.

2. Locate the Leak

Sub-steps:
- Clean the transmission area with a degreaser to identify the source of the leak better.
- Use a flashlight to inspect tight spots for fluid seepage.

3. Replace Transmission Pan Gasket

Sub-steps:
- Drain the transmission fluid into a catch pan by removing the drain plug.
- Remove the transmission pan bolts using a socket set.
- Carefully pull down the transmission pan and remove the old gasket.
- Clean the mating surfaces on both the pan and transmission.
- Position the new gasket and reinstall the transmission pan, tightening bolts to the manufacturer’s specifications (typically 10-12 ft-lbs).

4. Repair or Replace Transmission Cooler Lines

Sub-steps:
- Identify and remove the damaged transmission cooler line using the appropriate wrench.
- Install the new cooler line, ensuring all connections are secure.
- Check for proper routing of the line to avoid any abrasion against other components.

5. Replace Input/Output Shaft Seals

Sub-steps:
- Remove the drive shafts or axles if necessary to access the seals.
- Use a seal puller to remove the old seals carefully.
- Apply a light coat of transmission fluid to the new seals and install them into the transmission.
- Reassemble the drive shafts or axles, ensuring they are properly secured.

6. Refill with Transmission Fluid

Sub-steps:
- Reinstall the drain plug and fill the transmission with the appropriate type and amount of fluid (refer to the owner's manual).
- Start the engine and allow it to warm up, then check the fluid level and add more if necessary.
