Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent electrical issues during repair.

2. Drain Transmission Fluid

Place a drain pan under the transmission pan.
Remove the transmission pan bolts using a socket set.
Carefully lower the pan to allow fluid to drain completely. Dispose of the old fluid properly.

3. Replace Gasket and Inspect Pan

Clean the transmission pan thoroughly with a solvent to remove old gasket material.
Inspect the pan for cracks or damage; replace if necessary.
Apply a new transmission pan gasket, ensuring it is aligned correctly.

4. Inspect and Replace Seals

For leaking cooler lines, use a wrench to remove the lines.
Replace any damaged seals with new ones, ensuring they are properly seated.
Reattach the cooler lines and tighten to the manufacturer's torque specifications.

5. Refill Transmission Fluid

Reinstall the transmission pan and tighten the bolts to the specified torque value.
Refill the transmission with the appropriate type and amount of fluid (consult owner’s manual for specification).

6. Test Drive and Check for Leaks

Reconnect the battery.
Start the engine and let it idle; monitor for leaks.
Take the vehicle for a short test drive, then recheck the fluid level and inspect for any leaks.
