Solution

1. Preparation

Gather tools and parts needed for the repair.
Tools Required:
- Socket set
- Torque wrench
- Screwdriver set
- Transmission jack
- Oil catch pan
Safety Warnings:
- Ensure the vehicle is on a flat surface and use wheel chocks.
- Allow the engine to cool before working on the transmission.

2. Drain Transmission Fluid

Place an oil catch pan under the transmission pan.
Remove the transmission pan bolts using the socket set.
Carefully lower the pan to drain the fluid completely.

3. Inspect and Replace Seals

Inspect the transmission pan gasket and side seals for wear or damage.
Clean the mating surfaces on the transmission and the pan.
Install a new transmission pan gasket and side seals, ensuring proper alignment.
Torque the pan bolts to the manufacturer’s specifications (typically 10-12 ft-lbs).

4. Replace Transmission Filter (if applicable)

Remove the old transmission filter by unscrewing it.
Install a new filter, ensuring it is seated properly.

5. Refill Transmission Fluid

Refill the transmission with the appropriate type and amount of fluid (consult owner’s manual for specifics).
Start the engine and allow it to warm up, then check the fluid level again, adding more fluid if necessary.
