I own a 2001 automatic convertible,beautiful impecable piece of machinery, this car is 100% stock, but it is really fast.

Not long ago, I took my vette out for a Sunday afternoon drive, I had the urge to step on it coming out of a restaurtant in the keys, I shifted to 1st then proceeded to 2nd and eventually to 3rd.

About a week later I noticed a small drop of transmission oil towards the backend of the car, my neighbor suggested that a lot of transmissions have what is called an overflow escape and that in a couple of days it would go away, but it hasn't.

My question is. Could this leak be related to me accelarating the car so hard?

Second- As of late the car has now picked up a new noise, when I come to a full stop at a traffic light the car starts to tremble or purr and then as you shift to neutral it goes away.

Thirdly- The reading for the front left tire shows LXXX.

This is a great car, and maybe all of these little things may be nothing but I thought of asking my fellow compadres before I walked into a dealer and walked out with a huge bill and then found out I still have problems.

Your suggestions would really be appreciated.
