Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and secure it with wheel chocks.
Raise the vehicle using a jack and support it with jack stands.

2. Drain Transmission Fluid

Place a drain pan underneath the transmission pan.
Remove the transmission fluid drain plug (if equipped) or remove the transmission pan bolts to drain the fluid.
Allow the fluid to completely drain into the pan.

3. Remove and Inspect Transmission Pan

Remove all bolts securing the transmission pan.
Carefully lower the pan and inspect it for cracks or signs of wear.
Clean the pan and remove any old gasket material from both the pan and the transmission mating surface.

4. Replace Gaskets and Seals

Replace the transmission pan gasket with a new one.
Inspect and replace any worn or damaged seals, such as the input/output shaft seals.
Ensure that the sealing surfaces are clean to prevent future leaks.

5. Reassemble and Refill Transmission Fluid

Reattach the transmission pan and secure it with the bolts, tightening them to the manufacturer’s specified torque (check the service manual for the exact torque value).
Reinstall the drain plug if it was removed.
Refill the transmission with the correct type and amount of transmission fluid (check the owner’s manual for specifications).

6. Test for Leaks

Start the engine and allow it to reach operating temperature.
Shift through all gears to circulate the fluid.
Inspect the transmission area for any signs of leaks.
