Vibrating Sound
« on: May 27 2011, 10:36:25 AM »
When I'm cruising in the car, there is a vibrating noise just before the trans shifts.  The car is driving normally and shifting normally.  Any ideas?

No, I don't see how I could record it.

Got rid of the vibration.  I had zip-tied the trans cooler lines away from the crossover pipe and they were contacting the intercooler bracket further up, causing them to vibrate.

Damn vibraton sound is back.  I can't feel it, I can only hear it.  Whenever I accelerate, even a little, there's the vibrating sound.  The car is running and shifting fine.  What does a bad converter sound like?  I've had my damn stethescope and hose on every part of the darn car.  Can't find it.  Any ideas?

Doesn't do it when idling.  Only on acceleration.

Holy Crap!  It doesn't sound anything like that.  It's as if the inspection cover were loose (it's not).  Or the intercooler shroud (metal) were vibrating. It does it when I first accelerate, at any speed,  for about 20 seconds, and then it's gone.  I know this isn't much to go on, but I''m just looking for suggestions on what I might look at.

I didn't respond initially because this is a long shot, but- I had a friend who'd had a vibrating sound at idle because the mounting bolts for the crossmember (that supports the tranny at the rear) were loose.

Someone else suggested that and I checked the bolts.  They are tight.  Thanks

My bad converters usually sound like there are rocks bouncing around in them.

It may be time to disconnect the converter, push it back, and rev the engine to see if the sound is gone.

A lot of broken parts does not make you a racer; it makes you a slow learner.

Steve,
I sure it's not the converter.

sounds like a two man job...one to maintain the vibration and one to try to zero in on it.

Someone would have to ride under the hood, because it only does it under load.
