Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to ensure safety during repair.

Tools Required:

Socket set
Torque wrench
Pliers
Drain pan
Funnel
Clean rags or paper towels

2. Drain Transmission Fluid

Place a drain pan under the transmission pan.
Remove the bolts securing the transmission pan using the socket set.
Carefully lower the pan to drain the fluid completely into the pan.
Clean the pan and magnet inside to remove any debris.

3. Replace Gasket and Inspect Components

Remove the old gasket material from both the transmission and pan surfaces.
Inspect the transmission filter (if applicable) and replace if necessary.
Install a new gasket on the transmission pan.
Reattach the transmission pan and torque the bolts to manufacturer specifications (typically 8-10 ft-lbs).

4. Inspect and Replace Seals

Locate the output shaft seal and input shaft seal.
Use pliers to carefully remove any retaining clips or seals.
Install new seals, ensuring they are seated properly.
Apply a small amount of transmission fluid to the seals for lubrication.

5. Refill Transmission Fluid

Use a funnel to refill the transmission with the manufacturer-recommended fluid through the dipstick tube.
Check the fluid level using the dipstick after filling to ensure it is at the correct level.
