I can't say without looking because there are so many different types. But I am pretty sure you have an issue in the steering column possible below the ignition barrel. There is a pin / clip /rod or whatever your model has that engages when you turn the key. Yours it stuck "on " or broken. Hope this helps. Sam

If I think a belt driven component is making a noise, engine running, I use a long metal bar of some kind, I place the tip on component housing, the other end, I place on that bone behind my ear, it magnifies the sound. I listen to each component housing, see if I can locate the problem, that way. A mechanics stethoscope would probably work as well. You just have to be careful not to get anything caught in belt--pulleys or fan. Safety is your responsibility. It is possible the noise isn't coming from a belt driven component? Are you sure it isn't coming from under the dash?

Leaking transmission fluid can usually be traced to 1 or 2 problems:

1. leaking transmission line - a line could be bent or it could be leaking around a fitting, the most common place for a transmission line to leak
2. the gasket around the transmission pan is worn - this would cause leaking and having the filter and fluid changed should fix this problem

To answer your other question, YES it is possible to overfill the transmission fluid. Check the dipstick (with the car running) and ensure that the level stays between the recommended marks.
