Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to prevent electrical short circuits.

2. Drain the Transmission Fluid

Place a drain pan under the transmission pan.
Remove the transmission pan bolts using a socket set.
Carefully lower the pan to drain the old transmission fluid, ensuring to catch all fluid in the drain pan.

3. Inspect and Replace Gaskets/Seals

Remove the old gasket from the transmission pan and the mating surface on the transmission.
Inspect the pan for cracks or damage; replace if necessary.
Install a new gasket, applying a thin layer of gasket maker if required.

4. Replace Damaged Components

If any transmission lines or seals were found to be damaged during diagnosis, replace them as follows:
- Disconnect the damaged line using appropriate wrenches.
- Install the new line or seal and tighten securely to the manufacturer's torque specifications.

5. Refill Transmission Fluid

Reattach the transmission pan with new bolts, tightening them to the recommended torque specifications.
Refill the transmission with the appropriate type and amount of fluid as specified in the owner's manual.

6. Test for Leaks

Reconnect the battery and start the vehicle.
Allow it to reach operating temperature while checking for leaks around the transmission pan and lines.
If no leaks are detected, take the vehicle for a short test drive to ensure proper shifting and operation.
