Solution

1. Preparation

Gather tools and parts required for the repair.
Park the vehicle on a level surface and engage the parking brake.
Allow the engine to cool down before starting work.

2. Drain Transmission Fluid

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

3. Replace Gaskets and Seals

Tools Required: Gasket scraper, seal puller, torque wrench
Remove the old gasket material from the transmission pan and transmission surface using a gasket scraper.
Inspect and replace the transmission pan gasket if damaged.
If leaks are found at the seals (e.g., torque converter seal or output shaft seal), use a seal puller to remove the old seals and install new ones.

4. Reassemble Transmission Pan

Tools Required: Torque wrench
Place the new gasket on the transmission pan and position the pan back onto the transmission housing.
Install and hand-tighten the bolts initially, then use a torque wrench to tighten them to the manufacturer's specifications (consult service manual for torque values).

5. Refill Transmission Fluid

Tools Required: Funnel
Use a funnel to refill the transmission with the appropriate type and amount of fluid (consult the owner’s manual for specifications).
Start the engine and allow it to reach operating temperature, checking for leaks during this process.
