I'd start with a little preventative maintenance. At a minimum a drain and fill, hopefully there's a drain plug in the pan. Ideally, a pan drop with a new filter. Top off with new fluid.
Optional: add some Lubegard Red to it.
Option 2: Lubegard Dr. Shudder Fix
That's about it. Not too difficult. I need to do the same with the Matrix. Have a nice day kind sir.
