I noticed a noise when I depress the brake pedal in park. It's one audible click and if I put my hand on the shifter console at the same time I can feel one vibration (slight) that corresponds exactly to my braking in park. This only happens in park though. I believe in the past I could hear a very slight click but it's louder now. Is this anything to be concerned about? What could it be? Any help would be greatly appreciated. Thanks....

A little more information - year and make of vehicle, type of transmission (3spd auto/4spd auto?) - would probably help. If it's still shifting fine and the parking pall is still holding, there's probably nothing to worry about, but I am far from an expert on auto trannies.

It is a lockout mechanism so that you can't shift unless you have a foot on the brake. That's how the SVX works, and most other modern cars in general do too.

Northguy, it's a 96 AWD auto trans legacy 2.2 engine.

X35's right, it keeps you from accidently bumping the shifter out of park. I haven't had an automatic for several years but the ex wife had a 92 Honda Accord with the same lockout thing. Hers was a very noticeable click when you stepped on the brake. It also had a little keyhole beside the shifter that you could stick any key or even a screwdriver into and it would release it without using the brake.
