Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and secure with wheel chocks.
Disconnect the battery to prevent electrical issues.

2. Locate and Repair the Leak

Transmission Pan:
1. Place a drain pan underneath the transmission.
2. Remove the bolts securing the transmission pan using a socket wrench.
3. Carefully lower the pan and inspect for cracks or damage.
4. Clean the mating surfaces with a solvent.
5. Replace the transmission pan gasket if damaged.
6. Reinstall the pan and torque bolts to manufacturer's specifications (usually 10-15 ft-lbs).
Transmission Cooler Lines:
1. Inspect the cooler lines for any visible damage or loose fittings.
2. If damaged, remove the old lines using a wrench and replace with new ones.
3. Reattach the cooler lines securely.
Seals and Gaskets:
1. Check the input and output shaft seals for leaks.
2. If leaking, use a seal puller to remove the old seals.
3. Install new seals by pressing them into place using a seal driver.

3. Refill Transmission Fluid

Use a funnel to add the correct type of transmission fluid through the dipstick tube.
Check fluid level again with the dipstick after adding fluid.
