Question about 1999 Chevrolet Silverado 1500

99 silverado noise at higher rpm

A week ago, my truck started to make a loud clicking noise while I was driving. It sounded like a loose cat heat shield, somewhat like a rod knock. I climbed under the truck and had a friend bring the idle up. The sound is coming from the bellhousing, and I was able to see some fluid leak from a small plug on the drivers side. I had it checked, the flywheel and torque converter seem to be fine. I was told it would probably need to have the tranny rebuilt. Front pump, possibly? Or am I way off base?

You likely have a cracked flywheel. you cannot see the bolts without removing transmission so no one can tell if it's broken without taking it apart and looking at it. (If no cracks found between bolt holes, go ahead and do trans work, but I seriously doubt you will have to)

Rattling noise sportage 2008


Sorry for the late reply but, no, it is not related to a loose heat shield. It is a louder rattling sound more like a loose bearing vibrating inside either the transmission or the clutch assembly. Only between 1600 and 1900 rpm. and it is not present under ou over these rpm. The rattle desappear when I lock the 4X4. Dealer is out of solution!!

I just went through a similar problem with mine. Try plugs and wires first. Go have someone check for codes if the check engine light is on. If it throws a catalyst (cat) code you need catalytic converters. Just had mine done and its running better than ever. Good luck.

2004 Lincoln TC makes a loud rattling noise when put into gear. It's not noticeable when in Park. What could this be? It's not really a knocking sound - more like something is loose and rolling around.


catalytic high temp shield protecting bottom of car from the high heat. it maybe cracked or bent and is vibrating on the cat at certain rpm's. easy fix bend it back or away enough to prevent contact AFTER IT IS COLD

My 2003 suburban seems to run at a higher rpm.


Hummm, 2000 rpm does not seem high, really. But another item to look at is your FAN. The clutch fan fails and drives the fan full engauge. Sounds like a jeep...massive sounding, relating to engine RPM, but not necessarily different.

I mentiont his because a trans does not typically fail and give a few hundred RPM. Usually a slipping sensation is described....

sounds like a bad cat. converter. it could have some pieces of it rattling around anywere between cat and muffler.
also i have a ford ranger that did the same thing and i could not make the noise happen by banging etc i pulled my hair out because it was a short lived but loud noise at about 1500 rpm. finally i got some bailing wire and wrapped the heat shields with it one at a time.test drove and the noise did not vanish but it was greatly reduced. sure enough the heat shield on top of the cat had a spot weld that broke. took it to midas and had weld it up for me.

Nope. This is an Exhaust Leak. You need to replace the Exhaust Manifold Gaskets.
