  • Bad rattling sound coming from transmission area

    I have noticed a bad rattling sound, or more of a clinking sound when I go over a bumpy road coming from around the transmission area, I have raised the car up and got under it and looked but cannot find what the sound is coming from. The shifter is not moving any more than normal so I dont think that anythings broken, when I bought the car I had to replace a transmission bracket. The sound seems to be coming from the transmission area and is really loud, and usually just over bumps. It just started one day out of nowhere. Does anyone know how to fix this or what could be causing it? Or has anyone had the same problem? The car is a 97, V6, 5spd camaro with only a few modifications done but nothing to do with transmission or drivetrain.

    You replaced the Transmission Bracket?

    Check the Trans Mount. It's probably snapped in two.

      also check the cat and the heat sheild above the s-pipe. they dont typicly cling but they can rattle.

      are you maybe bottoming out?

        I will check both of those things tomorrow when I get under the car. I made a mistake though it wasnt a bracket that got replaced it was the transmission mount, and it was really obvious that it was broken because the shifter bounced up and down about 5 inches, it doesnt do that now so I dont think that it could be the mount again.

          I had the same problem. But found out it was a support under my muffler pipe. I removed it and it got rid of it. no more noise

              I just bent mine down, but it scrapes sometimes since the car is lowered.

                you might have a loose nut or bolt that is making the rattling sound, thats what happened to mine, i tightened it up and it never made the sound again. check it out.

                  Dont remove your tunnle brace it adds a little strength to the car and helps keep the shape of the tunnle. I had to modify mine because my exhaust was rubbing on it making a loud *** rattle.

                    I too have had to remove mine. When i would back up, it would have a bad sound really loud.

                      I suggest modifying it rather than completely removing it. First remove the 4 bolts holding it on and take it off. Next turn the car on and drive around the block if the noise is gone then it is the problem. now take a look at the brace and grind down where it is shiny (wherever its rubbing it will be shiney). Put it back on the car and try it out, if it still vibrates repeat till it doesnt rattle anymore. Once the rattle is gone take it off one last time and repaint it with high temp paint to prevent rust then put it back on and call it a day.

                          The factory one works just fine for the stresses put upon it but the aftermarket ones that rk and bmr sell allow for a lot more room. However i have i vert and can not use said aftermarket part (once again the vert gets owned on chasi mods).

                              I'm not totally aware of what type of bracketry is used on the tranny, but there could be something getting chewed up by the torque converter. Other than what has already mentioned I have no idea what it could be besides that.
