Solution

1. Preparation

Tools Required: Socket set, torque wrench, oil catch pan, funnel, UV dye (if necessary)
Gather materials and ensure the vehicle is parked on a level surface.
Disconnect the battery to avoid electrical issues during repairs.

2. Drain Transmission Fluid

Place an oil catch pan under the transmission pan.
Remove the transmission pan bolts using a socket wrench.
Carefully lower the pan and drain the fluid completely into the catch pan.

3. Inspect and Replace Gasket/Seals

Remove the old gasket from the transmission pan and inspect for any residue.
Check the transmission pan for warping or damage; replace if necessary.
If using UV dye, add it to the new transmission fluid before installation.
Install a new transmission pan gasket. Ensure it is correctly aligned.

4. Reinstall Transmission Pan

Raise the transmission pan back into position.
Hand-tighten the bolts, then use a torque wrench to tighten them to the manufacturer’s specifications (typically around 7-9 ft-lbs).
Refill the transmission with new fluid using a funnel; consult the owner’s manual for the correct type and amount of fluid.

5. Test for Leaks

Reconnect the battery and start the vehicle.
Allow the engine to run and shift through all gears.
Inspect the area around the transmission pan and cooler lines for any leaks.
