Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and ensure the engine is off and cool.
Wear safety gloves and goggles.

2. Drain Transmission Fluid

Tools Required: Socket set, drain pan.
Place a drain pan underneath the transmission pan.
Remove the transmission pan bolts using the socket set.
Carefully lower the pan and allow the old fluid to drain completely into the pan.

3. Inspect and Replace Gasket/Seals

Inspect the transmission pan gasket and any seals for wear or damage.
If damaged, remove the old gasket and clean the mating surfaces with a scraper.
Install a new gasket or seal, ensuring it is aligned correctly to prevent future leaks.

4. Reassemble Transmission Pan

Reinstall the transmission pan over the gasket.
Hand-tighten the bolts to secure the pan in place.
Use a torque wrench to tighten the bolts to the manufacturer's specified torque (usually around 10-12 ft-lbs, but consult the service manual for the exact value).

5. Refill Transmission Fluid

Tools Required: Funnel.
Using a funnel, refill the transmission through the dipstick tube with the appropriate type of transmission fluid as specified in the owner’s manual (usually Mercon V or equivalent).
Start the engine and let it run for a few minutes, shifting through all gears while checking for leaks.
