Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to prevent electrical issues during repairs.

2. Drain Transmission Fluid

Tools Required: Socket set, drain pan.
Use a socket set to remove the transmission pan bolts and carefully lower the pan to drain fluid into a drain pan.
Clean the transmission pan and magnet from any debris.

3. Replace Gasket and Seals

Parts Required: New transmission pan gasket, input and output shaft seals (if needed).
Remove the old gasket material from the transmission pan and the mating surface on the transmission.
If the input/output shaft seals are leaking, use a seal puller to remove the old seals and install new ones.
Apply a thin layer of gasket sealant on the new gasket, and place it on the transmission pan.

4. Reinstall Transmission Pan

Reattach the transmission pan using the socket set; torque the bolts to the manufacturer's specifications (usually around 8-12 ft-lbs).
Ensure the pan is properly aligned to avoid future leaks.

5. Refill Transmission Fluid

Parts Required: Correct type of transmission fluid (check owner's manual).
Use a funnel to refill the transmission fluid through the dipstick tube until it reaches the correct level.
Start the engine and let it run for a few minutes, then check the fluid level again and add if necessary.
