Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and the engine is off.
Put on safety glasses and gloves.

2. Drain Transmission Fluid

Place a drain pan under the transmission pan.
Remove the transmission pan bolts using a socket set.
Carefully lower the pan and allow the old transmission fluid to drain completely.

3. Inspect and Replace Gaskets/Seals

Check the transmission pan gasket for damage and replace it if necessary.
Inspect the input/output shaft seals and replace them if any leaks are found.
Clean the mating surfaces of the transmission and pan to ensure a proper seal.

4. Reassemble Transmission Pan

Position the new or cleaned pan gasket on the transmission pan.
Reattach the transmission pan and tighten the bolts to the manufacturer’s specifications (typically around 10-12 ft-lbs; check specific torque values for your vehicle).
Refill the transmission with new fluid through the dipstick tube using the recommended transmission fluid type.

5. Test for Leaks

Start the engine and let it run until it reaches operating temperature.
Check for leaks around the transmission pan and seals.
If no leaks are found, take the vehicle for a short test drive, then recheck for leaks.
