Solution

1. Preparation

Tools Required: Safety glasses, gloves, jack stands, and a catch pan.
Ensure the vehicle is parked on a level surface and the engine is off. Allow the engine to cool if previously running.

2. Raise the Vehicle

Sub-steps:
- Use a jack to lift the vehicle and secure it with jack stands.
- Make sure the vehicle is stable before proceeding.

3. Locate the Leak Source

Sub-steps:
- Visually inspect the transmission pan and surrounding areas for fluid seepage.
- If necessary, clean the area with a degreaser to better observe where the leak is originating.

4. Replace Seals and Gaskets

Sub-steps:
- If the transmission pan gasket is leaking, drain the transmission fluid into a catch pan.
- Remove the transmission pan bolts using a socket set and carefully detach the pan.
- Remove the old gasket and clean the mating surfaces.
- Install a new gasket and reattach the pan, tightening bolts to the manufacturer’s specified torque settings (typically around 10-12 ft-lbs).
- If the input/output shaft seals are leaking, use a seal puller to remove the old seals and install new ones, ensuring they are properly seated.

5. Refill Transmission Fluid

Sub-steps:
- Refill the transmission with the appropriate type and quantity of fluid as specified in the owner’s manual.
- Start the engine and allow it to warm up before checking fluid levels again.
