Solution

1. Preparation

Gather tools: socket set, torque wrench, transmission fluid, funnel, cleaning rags, and safety gloves.
Ensure the vehicle is parked on a level surface and the engine is turned off and cooled down.

2. Identify and Repair the Leak Source

Inspect Seals and Gaskets:
1. Locate the transmission pan and inspect the gasket for damage or wear.
2. If the gasket is damaged, proceed to remove the transmission pan.
Remove Transmission Pan:
1. Use a socket set to remove the bolts securing the transmission pan.
2. Carefully lower the pan and allow any residual fluid to drain into a container.
Replace Gasket:
1. Clean the mating surfaces of the transmission and pan thoroughly with a cleaning rag.
2. Place a new gasket onto the transmission pan.
Reinstall Transmission Pan:
1. Lift the pan back into position and secure it with bolts.
2. Torque the bolts to the manufacturer's specifications (typically around 10-12 Nm, but check specific guidelines).

3. Repair or Replace Fluid Lines (if applicable)

Inspect and Replace Lines:
1. If cooler lines are leaking, use a socket set to disconnect the lines from the transmission.
2. Replace any damaged lines with new ones, securing them in place.

4. Refill Transmission Fluid

Use a funnel to add the recommended type of transmission fluid through the dipstick tube until it reaches the proper level.
Start the engine and let it run for a few minutes, shifting through all gears to circulate the fluid.
