Solution

1. Preparation

Gather tools and materials: rags, clean container, flashlight, and safety glasses.
Ensure the vehicle is parked on a flat surface and the engine is cool.

2. Inspect Transmission Pan

Tools Required: Socket set, torque wrench
Remove any undercarriage protection panels if applicable.
Clean the area around the transmission pan to prevent contamination.
Check the pan bolts for tightness; if loose, tighten to manufacturer specifications (consult the service manual for torque values).
If leaks are detected, replace the transmission pan gasket.

3. Check Transmission Cooler Lines

Tools Required: Wrench set
Inspect the cooler lines for damage or corrosion.
If leaks are found, replace the damaged lines with new OEM parts.
Ensure all connections are tight and use new washers if needed.

4. Inspect Axle Seals

Tools Required: Seal puller (if necessary), socket set
Check the axle seals for signs of fluid seepage.
If leaking, remove the axle and replace the seals with new ones.
Apply a thin layer of transmission fluid to the new seals before installation to aid in sealing.

5. Test Drive

After repairs, refill the transmission fluid to the proper level (consult the owner's manual for the correct fluid type and amount).
Test drive the vehicle to ensure the transmission operates smoothly and check for any new signs of leaks.
