Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the engine is cool.
Gather necessary tools and parts.
Disconnect the battery to ensure safety while working.

2. Drain Transmission Fluid

Place a drain pan under the transmission pan.
Remove the transmission pan bolts using a socket set.
Carefully lower the transmission pan to drain any remaining fluid.

3. Replace Gaskets and Seals

Remove the old gasket from the transmission pan and the mating surface on the transmission.
Clean the surfaces with a suitable solvent to ensure a good seal.
Install a new gasket on the transmission pan.
Inspect and replace any worn seals, including the input and output shaft seals, as needed.

4. Reinstall Transmission Pan

Position the transmission pan back onto the transmission.
Hand-tighten the bolts initially, then torque them to the manufacturer’s specifications (typically 10-15 Nm).
Ensure there are no gaps or misalignments in the gasket.

5. Refill Transmission Fluid

Using a funnel, refill the transmission with the appropriate type of fluid specified by the manufacturer (usually a DCT or ATF fluid).
Start the engine and allow it to idle, shifting through all gears to circulate the fluid.
Check the fluid level again and top off as necessary.

6. Final Inspection

Reconnect the battery.
Start the engine and inspect for any leaks around the pan and seals.
Test drive the vehicle to ensure smooth operation and verify that the leak has been resolved.
