Just returned from lunch. 95 degrees.
Parked the car. Shifted to park (car is not moving, of course). About 2 seconds after the care was placed in park I hear a loud clunk. Car is still running. I shift to drive and then back to park. No clunk.

First time this has ever happened. Car has 60K miles. I have done drain and fill 3 times at 20K and a single drain and fill at 40K and 58K. All with DW1. Fluid level is right on the numbers.

Thanks

 

could be a failing motor or transmission mount, or it could be the A/C turning on.

 

Frankly, unless it happens again I just wouldn't worry about it.
