Disconnect the battery to avoid electrical issues during repair.

2. Inspect and Replace Transmission Pan Gasket

Tools Required: Socket set, torque wrench, gasket scraper, clean rags, transmission fluid.
Remove the transmission pan bolts using a socket wrench.
Carefully lower the transmission pan, allowing any residual fluid to drain into a container.
Clean the mating surfaces of the transmission and the pan thoroughly with a gasket scraper.
Place the new gasket on the transmission pan and align it properly.
Reinstall the transmission pan, tightening the bolts in a crisscross pattern to the specified torque value (consult service manual for exact torque specifications).

3. Inspect and Replace Transmission Cooler Lines (if necessary)

Tools Required: Wrench set, fluid catch container.
Locate the transmission cooler lines and inspect for any leaks or cracks.
If damaged, use a wrench to disconnect the lines from the transmission and the cooler.
Install new transmission cooler lines, ensuring all connections are tight and secure to prevent future leaks.

4. Refill Transmission Fluid

Tools Required: Funnel.
Using a funnel, refill the transmission with the appropriate type of transmission fluid as specified in the owner's manual.
Start the engine and let it idle for a few minutes, then check the fluid level again, adding fluid as necessary.
