Solution

1. Preparation

Tools Required: Socket set, torque wrench, transmission fluid pump, drain pan, UV dye kit (if needed).
Verify the vehicle is on a level surface and secure it with wheel chocks.
Disconnect the battery to ensure safety while working on electrical components.

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 to drain the fluid completely.

3. Inspect and Replace Gaskets/Seals

Inspect: Check the transmission pan gasket and any seals for wear or damage.
Replace: If damaged, remove the old gasket and clean the mating surfaces thoroughly.
Apply a thin layer of gasket maker or install a new gasket as per manufacturer’s specifications.

4. Repair Leaks

If leakage is found in the transmission cooler lines, replace or tighten the damaged lines or fittings.
For other seals, such as the input/output shaft seals, remove the components as necessary to replace the seals.

5. Reinstall Transmission Pan

Once all repairs are made, raise the transmission pan back into position.
Tighten the transmission pan bolts to the manufacturer’s specified torque value, ensuring even pressure around the pan.

6. Refill Transmission Fluid

Use a transmission fluid pump to refill the transmission with the correct type and amount of fluid as specified in the owner's manual.
Reconnect the battery.
