There is no check [engine](/topics-engine-chevy/) lights on or vehicle performance issues correct?

No ch engine lightThank you, \*\*\*\*\* \*\*\*\*\* textingWould my engine light go on if it was the [catalytic converter](/topics-catalytic-converter-chevy/)
Automotive Expert
No need to call the site asks that not me I prefer text as well. The engine light would not come on all the time if the catalytic convertor was bad. But some good news you most likely have a heat shield that came loose and all you need to do is have it removed very simple fix and very common. Seen it all the time. I would start here.

My transmission Cage had to be replaced at one time it sounded almost the same but when they changed my transmission casing it sounded more in the back where as this noise is sounding more in the frontOkay I have one more question if you don't mindWhat other indication would there be if it was my catalytic converter
Automotive Expert
Yes I'm leaning towards that heat shield or when work was done to the vehicle they left something loose. Best way to diagnose it is up on a lift tech under it and one inside and hold it in reverse to duplicate the noise to pinpoint it. If it was the converter it would run rough and be sluggish as well.

Would it be better to take it to the dealer or just a regular mechanic and what kind of mechanicalso could it possibly be my [muffler](/topics-muffler-chevy/)
Automotive Expert
Dealer as a regular shop will try to upsell you the world the dealer will as well but tell them you just want the noise fixed. Muffler would be in the back .

I see thank you so much can you recommend anyone
Automotive Expert
Just when you go to the dealer ask to speak top the tech whos working on your car. Tell him you just want the noise fixed no upsells maybe give him or her 20 bucks and you should be fine with the correct fix.

Ok I will women can be easy targets.
