2. Inspect Transmission Pan

Sub-steps:
1. Locate the transmission pan under the vehicle.
2. Clean the exterior of the pan with a rag to remove any dirt or debris.
3. Look for signs of wetness or fluid stains around the pan edges.
4. If the pan is leaking, proceed to replace the pan gasket or the pan itself.

3. Check Seals and Gaskets

Sub-steps:
1. Inspect the front and rear transmission seals for leaks.
2. If any seals appear worn or cracked, replace them.
3. Use a torque wrench to ensure that the transmission pan bolts are tightened to the manufacturer's specifications.

4. Examine Cooler Lines

Sub-steps:

2. Look for any signs of wear, such as cracks or corrosion.
3. If any lines are damaged, replace them with new lines.

5. Refill Transmission Fluid

Sub-steps:
1. If low fluid levels are confirmed, add the appropriate type of transmission fluid to the dipstick tube.
2. Use a funnel to prevent spills and ensure accurate filling.
3. After adding fluid, run the engine and cycle through the gears to circulate the fluid, then recheck the level.
