I've recently found that whenever i shift out of park, (I have an automatic), that it always seems to make a kind of a "ping" noise. It also happens very frequently when i gear down. I use nothing lower than 93 octane in my 1999 Z28, but that doesn't really seem to make much difference. I even put in octane booster making it about 100 Octane. Do I need to change my transmission fluid? I have 25,088 miles, with recently changed oil at 24,980. What if anything is wrong? Could it be my transmission?? Engine detonation?? Is this normal? Please help, <img border="0" title="" alt="[Roll Eyes]" src="images/icons/rolleyes.gif" /> Thanx

Aluminum driveshaft?? That's what it sounds like.

Does my car have an alluminum driveshaft? If it is the problem, how do I fix it? Totally replace it??? Any other idea's of what it may be?

It's wierd, cause once in a while it doesn't even make a noise(some days are louder than others). I've done this and had temporary success- i start my engine, keep my foot on the brake, and gradually go from park to reverse, to neutral, to drive, then 3rd, 2nd, 1st, than back up again. Then when i take my foot off the brake i wait a second, and I place it back on and go into reverse without any noise. Could it be engine detonation?

I have this same thing happen to me in my 2K SS A4. I am not real sure about what it is but I have heard other F-bodies do it too. I dont think it is the motor I think it is the transmission. I am not worried about cause I predict it is just the car going into gear. But let me know if you find out it is dangerous...!!! <img border="0" title="" alt="[Confused]" src="images/icons/confused.gif" /> But I dont think it is

Thanks Mike, I thought it was just the tranni too, but its sometimes loud. I don't know many others with F-Body's so it's get to know that it's a universal observation. Oh yea by the way, Nice lookin' ride! <img border="0" alt="[hail]" title="" src="graemlins/gr_hail.gif" />
